Season 8: Episode 174: The One With Rachel's Date

Ross is horrified to learn that Rachel is headed out on a date with a handsome soap-opera actor (guest star Johnny Messner) -- especially since she is pregnant with his child while Phoebe is attracted to a cute but klutzy sous-chef -- and protests when Monica wants to fire him. Elsewhere, Chandler torpedoes the promotion of a distant co-worker (guest star Chris Parnell) who's mistakenly been calling him "Toby" for five years.
