Alex, at loose ends after the wedding fiasco, hijacks Penny for a series of "girls' night outs," including a cooking class with an obnoxious chef. Dave moves in with Max, who convinces him to hunt down the interloper who ruined his wedding . . . . if only either of them can sober up enough to remember his name. And Jane, fearful that she'll end up like her sister, talks husband Brad into a night on the town.
