This first episode of a two-part story (originally seen as the first half of an hour-long telecast) occurs on the night before the wedding of Joe (Tim Daly) and Helen (Crystal Bernard). Joe has promised Helen that he will not indulge in a wild bachelor party -- but Helen has made no such promise herself, and does she have a great time! Meanwhile, Joe's own "prenup" party is a disaster...for everyone but Brian (Steven Weber) and Casey (Amy Yasbeck). ~ Hal Erickson, Rovi
