This should probably have been the first post on Losing it, but since I only just found it, I’ll have to add it now.
Random clickage via Bad Astronomy led me to xkcd – A webcomic of romance, sarcasm, math, and language, which contains much that is odd, quirky, funny and generally interesting. The artist is publishing it under a Creative Commons licence, which is why I’m including the cartoon rather than just a link.
Even if you don’t like the cartoons, you might find the legal disclaimer thingy amusing:
Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).
