Beerfest, the game

I've often though it would be fun to play a one shot or a short series of adventures of The Big Lebowski. Not nessisarily the actual characters fromthe movie. (Although perhaps as NPC's) But as their own people gettingin crazy adventures, and bowling. Well with my interest in Oktoberfest. I came to a startling conclusion. I should run a Beerfest game. What ever the system. Have a drinking skill. Quarter bounce skill. Ping Pong skill. Bluff people. Taunting, and what not. It could be fun as hell.
But that leaves questions. What system? Would quarter bounce and ping pong be dealt with as skills? Or as a modified version of combat?
Hmmm... Definitely some things to ponder.
