Programming jokes.

This is rather off-topic, but I hope no one will mind too much.

Anyone have any good programming jokes? Personally, I'm a fan of "Old C programmers never die; they're just cast into void" and "There are 10 kinds of people: those who understand binary and those who don't." Plus, I'm convinced there needs to exist a good joke that begins, "A database, operating system, and web browser walk into a bar," and I'm hoping someone here will come up with one. :-)
