The One Where Chandler Can't Remember Which Sister

Plot:

Rachel hates her new 'fashion' job too as another dead end- Monica isn't the most sympathetic audience in her job serving with fake boobs, but there she meets Mark, a Bloomingdale's executive who may get her a job in his department; of course Ross believes his intent must be dishonorable. At Joey's birthday party Chandler drinks too much vodka now Janice is back with her ex, gets intimate with one of Joey's seven sisters and can't even remember which one- more proof for Ross; he must go over to break up at the Tribbiani house where grandmother doesn't even let him get a word in.
