88 of the Best Programmer Jokes

Programmer JokesIn this article, I’ve listed a whole bunch of programmer jokes that only programmers will understand!

Most of these jokes have been sourced from StackOverflow and Reddit, with many of them sent to me by other programmers in my career.

There’s some good ones, some lame ones, and some that are so old they’re probably not funny any more.



Programming Language Jokes

“Knock, knock.”

“Who’s there?”

very long pause….

“It’s the year 9999 – and you know Cobol.”


The C language combines all the power of assembly language with all the ease-of-use of assembly language.


Differences between languages:

  • Ada : You aim at your foot and pull the trigger, but the safety stops the gun from firing. The safety won’t budge until you tag your foot with a sign reading “”Bullet Hole in this foot””, and call the paramedics. You do so, then shoot yourself in the foot.
  • C : The gun comes in 38 pieces, with a set of assembly instructions. After painstakingly assembling the pieces, you pull the trigger and the gun promptly backfires and blows your head off.
  • Assembly : The same as C, except you have to hand-machine all the pieces as well. When you pull the trigger, your whole house explodes.
  • Java: You break into someone else’s home and steal their water pistol. You then make a child gun that uses .38 rounds instead of water. When you pull the trigger on the child gun, nothing happens to you, but everyone who visits your house gets shot in the foot.
  • Basic : You aim the gun at a straight horizontal and pull the trigger, which causes a stream of water to be squirted straight down onto your foot.
  • Perl : You aim the gun at your foot and pull the trigger. There is no explosion, but gravity causes the bullet to slide out of the barrel and bounce off your foot.
  • Lisp : You do a small part of the remaining work involved in shooting yourself in the foot. You then call yourself, and tell yourself to shoot yourself in the foot.
  • Pascal : The same as Ada, except when you pull the trigger a little sign pops out reading “”BANG!””.
  • C++ : The same as Java, except you try to build the parent water pistol using the gun tools from the C gun. When you pull the trigger on the child gun, the parent C gun explodes, spraying water everywhere, including the chamber of the child gun. This causes the child gun to backfire, blowing your head off.
  • Visual C++ : The same as C++, except that the bullets, the gun parts, the tools you use to put it together, the hospital you get taken to afterwards, and the ambulance that takes you there are all owned by the same company.
  • APL : Whenever you pull the trigger, no matter where you aim the gun, the bullet ricochets off of 13 objects and lodges in your foot. The gun has been examined by ballistics experts, mechanical engineers, and even the person who made it, and none of them can figure out how it works.
  • FORTRAN : When you aim the gun at your foot and pull the trigger, a table indexing error causes the gun to shoot its firing pin into your foot instead of the bullet.

A young Programmer and his Project Manager board a train headed through the mountains on its way to Wichita. They can find no place to sit except for two seats right across the aisle from a young woman and her grandmother.

After a while, it is obvious that the young woman and the young programmer are interested in each other, because they are giving each other looks. Soon the train passes into a tunnel and it is pitch black. There is a sound of a kiss followed by the sound of a slap.

When the train emerges from the tunnel, the four sit there without saying a word.

The grandmother is thinking to herself, “It was very brash for that young man to kiss my granddaughter, but I’m glad she slapped him.”

The Project manager is sitting there thinking, “I didn’t know the young tech was brave enough to kiss the girl, but I sure wish she hadn’t missed him when she slapped me!”

The young woman was sitting and thinking, “I’m glad the guy kissed me, but I wish my grandmother had not slapped him!”

The young programmer sat there with a satisfied smile on his face. He thought to himself, “Life is good. How often does a guy have the chance to kiss a beautiful girl and slap his Project manager all at the same time!”


A physicist, an engineer and a programmer were in a car driving over a steep alpine pass when the brakes failed.

The car was getting faster and faster, they were struggling to get round the corners and once or twice only the feeble crash barrier saved them from crashing down the side of the mountain. They were sure they were all going to die, when suddenly they spotted an escape lane. They pulled into the escape lane, and came safely to a halt.

The physicist said “We need to model the friction in the brake pads and the resultant temperature rise, see if we can work out why they failed”.

The engineer said “I think I’ve got a few spanners in the back. I’ll take a look and see if I can work out what’s wrong”.

The programmer said “”Why don’t we get going again and see if it’s reproducible?”


Once upon a time there was a shepherd looking after his sheep on the side of a deserted road. Suddenly a brand new Porsche screeches to a halt. The driver, a man dressed in an Armani suit, Cerutti shoes, Ray-Ban sunglasses, TAG-Heuer wrist-watch, and a Versace tie, gets out and asks the Shepherd:

Man: “If I can tell you how many sheep you have, will you give me one of them?”

The shepherd looks at the young man, and then looks at the large flock of grazing sheep and replies, “Okay.”

The young man parks the car, connects his laptop to the mobile-fax, enters a NASA Webster, scans the ground using his GPS, opens a database and 60 Excel tables filled with logarithms and pivot tables, then prints out a 150 page report on his high-tech mini-printer. He turns to the shepherd and says, “You have exactly 1,586 sheep here.”

The shepherd cheers. “That’s correct, you can have your sheep.”

The young man makes his pick and puts it in the back of his Porsche. The shepherd looks at him and asks, “If I guess your profession, will you return my animal to me?”

The young man answers, “Yes, why not?”

Shepherd: “You are an IT consultant.”

Man: “How did you know?”

Shepherd: “Very simple. First, you came here without being called. Second, you charged me a fee to tell me something I already knew, and third, you don’t understand anything about my business. Now can I have my dog back?”


How to catch an Elephant in the Africa

  • MATHEMATICIANS hunt elephants by going to Africa, throwing out everything that is not an elephant, and catching one of whatever is left.
  • EXPERIENCED MATHEMATICIANS will attempt to prove the existence of at least one unique elephant before proceeding to step 1 as a subordinate exercise.
  • PROFESSORS OF MATHEMATICS will prove the existence of at least one unique elephant and then leave the detection and capture of an actual elephant as an exercise for their graduate students.
  • COMPUTER SCIENTISTS hunt elephants by exercising Algorithm A:
    • Go to Africa.
    • Start at the Cape of Good Hope.
    • Work northward in an orderly manner, traversing the continent alternately east and west.
    • During each traverse pass,
    • Catch each animal seen.
    • Compare each animal caught to a known elephant.
    • Stop when a match is detected.
  • EXPERIENCED COMPUTER PROGRAMMERS modify Algorithm A by placing a known elephant in Cairo to ensure that the algorithm will terminate.
  • ASSEMBLY LANGUAGE PROGRAMMERS prefer to execute Algorithm A on their hands and knees.
  • ENGINEERS hunt elephants by going to Africa, catching gray animals at random, and stopping when any one of them weighs within plus or minus 15 percent of any previously observed elephant.
  • ECONOMISTS don’t hunt elephants, but they believe that if elephants are paid enough, they will hunt themselves.
  • STATISTICIANS hunt the first animal they see N times and call it an elephant.
  • CONSULTANTS don’t hunt elephants, and many have never hunted anything at all, but they can be hired by the hour to advise those people who do.
  • OPERATIONS RESEARCH CONSULTANTS can also measure the correlation of hat size and bullet color to the efficiency of elephant-hunting strategies, if someone else will only identify the elephants.
  • POLITICIANS don’t hunt elephants, but they will share the elephants you catch with the people who voted for them.
  • LAWYERS don’t hunt elephants, but they do follow the herds around arguing about who owns the droppings.
  • SOFTWARE LAWYERS will claim that they own an entire herd based on the look and feel of one dropping.
  • VICE PRESIDENTS OF ENGINEERING, RESEARCH, AND DEVELOPMENT try hard to hunt elephants, but their staffs are designed to prevent it. When the vice president does get to hunt elephants, the staff will try to ensure that all possible elephants are completely pre-hunted before the vice president sees them. If the vice president does happen to see a elephant, the staff will compliment the vice president’s keen eyesight and enlarge itself to prevent any recurrence.
  • SENIOR MANAGERS set broad elephant-hunting policy based on the assumption that elephants are just like field mice, but with deeper voices.
  • QUALITY ASSURANCE INSPECTORS ignore the elephants and look for mistakes the other hunters made when they were packing the jeep.
  • SALES PEOPLE don’t hunt elephants but spend their time selling elephants they haven’t caught, for delivery two days before the season opens.
  • SOFTWARE SALES PEOPLE ship the first thing they catch and write up an invoice for an elephant.
  • HARDWARE SALES PEOPLE catch rabbits, paint them gray, and sell them as desktop elephants.

A group of programmers and marketers were travelling to a trade show on a train. Each of the marketers had bought a ticket, but the programmers had only bought one ticket for the lot of them.

One of the programmers was keeping a lookout, and when the conductor neared their car he called out “The conductor’s coming!” and all of the programmers piled into the train’s lavatory and closed the door. The conductor took the tickets of all of the marketers, and then knocked on the lavatory door and called “Ticket please.” The programmers slid their ticket under the door, and the conductor took it and left.

The programmers were laughing at the marketers for the rest of the trip, and the marketers felt like idiots.

On the way back, the marketers decided they would use the same trick and only bought one ticket for them. But this time, the programmers didn’t buy a single ticket! Again, one of the programmers kept a lookout for the conductor. When he called “Conductor coming!” all of the programmers piled into one lavatory, and all of the marketers shut themselves into another lavatory.

One programmer came back out of his lavatory, knocked on the other door, and said “Ticket please!”


Three men are talking: A programmer, a doctor, and a lawyer.

The lawyer says, “Man, the only way is to have a mistress. With all these divorce suits, it’s terrible. The only way is to have a mistress.”

The doctor says, “Are you kidding? With all the STDs out there, you want a wife and that’s it.”

The programmer says, “You need both a wife and a mistress. Because when you’re not with the mistress, she’ll assume you’re with your wife, and when you’re not with your wife, she’ll assume you’re with your mistress, and THAT leaves you more time for programming!”
