While drunk, Chandler (Matthew Perry) has a fling with one of Joey's (Matt LeBlanc) sisters. Once his head clears up, he can't remember which sister was the lucky one (Gina or Dina?). On other fronts, Phoebe's (Lisa Kudrow) new date is both very charming and very loud. And Rachel (Jennifer Aniston) is offered a job at Bloomingdale's by a handsome stranger, arousing Ross' (David Schwimmer) suspicious nature. Steven Eckholdt makes his first series appearance as Mark. ~ Hal Erickson, Rovi
