Recently I've been enjoying xkcd, aptly described on its site as "A webcomic of romance, sarcasm, math, and language." This example is "Fall Apart", from 5th May last year.
It's not for everyone, by any means, but if you've ever been a geek, or loved one, you'll find something here to like. Spoiler Alert is one of the more accessible examples of the strip's sense of humour. (Note: it means what it says.)
