Jokes about esoteric topics like programming and computer science are best communicated through memes. Otherwise, you've got yourself with a bunch of corny knock-knock jokes that nobody under 55 will enjoy. For instance, the following jokes are what you could be getting if you got your programming humor elsewhere.
"Programmer goes to his computer. He's working at home. Right now, he's coding a music player for his own system. He tests it, seeing that it works. His friend calls him and says: "What are you listening to right now?" The programmer replied: "I'm listening to The Script."
"A movie about the maximum function in coding and signal transformation applications in road planning: Math Max Fourier Road."
"How did the elephant destroy the database? His truncate it."
Weren't those awful? One might argue that they would never have had to look at those if they didn't open this page up, but have no fear! The following cornucopia of programming memes will be enough to make up for it and then some.
