Having just praised some pretty terrific artists, here's a cartoon I love that, well, doesn't exactly rely on draftsmanship. And it's not always Safe For Work or Fun For The Whole Family. And it's often too geeky for me to understand.

"xkcd:A webcomic of romance, sarcasm, math, and language." Geez, how can you go wrong?
