Ultimate Frisbee (like soccer, with a Frisbee instead of a ball) is exhilarating enough on its own, but try playing with the coed team Pompeii's Children. This squad has struck a perfect balance between being highly athletic and yet awfully silly. Players have been known to make bets among themselves in which the loser is forced to play wearing a muumuu. They've also devised a whole fantasy league based upon the team's real-life lineup. Pompeii hosts practice on Tuesdays and pickup games on Fridays in Hollywood (everyone, including beginners and females, welcome) and travels to other cities for the occasional tournament. There, the team usually lands third place but almost always takes home the trophy for "Spirit of the Game." Pompeii's dominance in the spirit category might have something to do with its post-game ritual of pouring vodka and orange juice straight from containers into the mouths of opponents. Or it could be because of the Slip N' Slide they tote around, greasing it up with soap and water for layout contests (feats of athleticism that involve players leaping horizontally in midair for the disc). What we know for sure is that for ten long years now, team captain Kristin Deffler has created tons of good, clean, healthy fun — all around a simple piece of plastic.
