If you’ve never checked out the rec.humor newsgroup, I’d highly recommend them. There are some especially humorous jokes for computer scientists/programmers. Here are two that I particularly like:
* [[http://www.netfunny.com/rhf/jokes/88q1/13785.8.html|The Flamer's Bible]]
* [[http://www.netfunny.com/rhf/jokes/new89/halting.760.html|The Halting Problem is solvable]]
If you’re really interested, you can also buy a collection of the best jokes from the this newsgroup from the past two decades for around 10 bucks. Checkout [[http://www.netfunny.com/rhf]]
