This is the penultimate episode before the infamous "The One Where Ross and Rachel Take a Break."

Phoebe realizes Leslie hasn't changed and ends the partnership for good, choosing her integrity over a professional comeback. 2. Chandler’s "Leg" Issue

Chandler tries to be mature about her artificial limb, but when Ginger finds out Chandler has a "third nipple" (a recurring Season 3 gag), she is the one who gets freaked out and dumps him . 3. Ross vs. Mark

This episode provides the "professional" version of "Smelly Cat" used in the commercial, which Phoebe finds repulsive.

"She’s a jingle writer. She’s the devil! She’s the devil in a polyester blend!"
