Friends (1994 - 2004): The One with the Boobies

Chandler accidentally walks in on Rachel after a shower and sees her breasts, leading to a series of shower peepings. Phoebe's new psychiatrist boyfriend, Roger, depresses and angers everyone. Joey finds out his dad has been having an affair with Ronni, a pet mortician, for six years; he insists his dad either break it off or confess, but it turns out his mom already knew--and didn't want it to stop.
