Well, a search on the net finds lots of these 'remarks'. Best reference about programmers in general is however The Jargon File. The entries on The Story of Mel, Real Programmer and A portrait are interesting.

And I just love the entries on Perl, especially Swiss!

In short, programmers in general have a weird sense of humor, p.e. *noone* of my non-programmer friends think the number 42 is funny!
