Susie "Underpants" Moss (Julia Roberts): an old childhood friend of Chandler, who's working on the production of a movie, and with whom Chandler has a colored history: when they were in elementary school, Chandler pulled up Susie's skirt when she was on stage, revealing her underwear to the entire school, and she never lived it down until she graduated high school. They arrange a date, Chandler unsuspecting that it is a plot to get revenge. After convincing him to wear her panties, Susie takes him out to dinner, undresses him in the men's room, and takes off with his clothes—leaving him in a bathroom stall wearing nothing but her panties. She is never seen again. Julia Roberts and Matthew Perry briefly dated in real life.
