Karen hosts a party for her birthday. As usual, it's high class all the way-- and that's not the only thing that's high.
Karen's well-meaning but inept friends don't know how to act and just embarrass themselves to ever greater degrees. When the wheels come off, they head for that universal symbol of solace, the bathroom.
Soon the washroom becomes a party of its own, as everybody and their sister winds up in there. Tensions flare and the talcum powder flies.
This is the second time in the eighth season that the show was done live, in two sessions, one for East Coast viewers and one for those in the West.
The powder fight alone is worth the price of admission. It's a very funny episode, and one of the highlights of the final year.
