People playing chess on roller coasters

ChessCoaster quote [Fans of the xkcd webcomic have taken up the challenge laid out in one of the strips and are riding roller-coasters with glued-together chess-sets. One of my all-time fave strips from xkcd is Chess Photo. The gag is that a prankster is gluing down his chess-pieces so that he can get on a roller-coaster, sit in the front seat, and be photographed deep in concentration over a gnarly chess-problem while behind him the rest of the coaster's riders go berserk].

Really Complicated Sex Fun

LINK quote [A great cartoon, and the title on the original reads, “Oh, I think this word might mean ‘Crisco’!” I don’t know if the author of XKCD takes requests, but he can treat this as my vote for more sex cartoons].

Map of Online Communities

LINK quote [By popular demand: order a poster of the Online Communities map. It will be 25"x24", full-page, and you'll be able to read all the little city labels. It also includes other little other points of interest mapped exclusively for the poster!].
