And speaking of improv games, back in the old National Velveeta days, one of my favorite improv games was World's Worst, so I'm sure that's part of why I snapped up Mark Frauenfelder's The World's Worst : A Guide to the Most Disgusting, Hideous, Inept, and Dangerous People, Places, and Things on Earth. I breezed through it in a train ride and I've throw it into the bathroom for other's browsing pleasure.

Mark also recommends good things at Mad Professor.
