I was procrastinating at work yesterday, and came across a link to this on Slahdot. Going up one level from that URI takes you to a page with some more stuff. Mm stuff. I liked the page of Bart Simpson blackboard quotes, but the best that I've found so far is this page about how to shoot yourself in the foot in different programming languages.

Here's one of the better ones:

Unix
% ls
foot.c foot.h foot.o toe.c toe.o
% rm * .o
rm: .o: No such file or directory
% ls
%

I also like the Ada one.

Update:

This page is also worth a look.. :)
