In Friends, what is the name of the character who first says “Smelly Cat” with Phoebe?

Stephanie Schiffer is the character who first performs “Smelly Cat” with Phoebe in Friends.

Stephanie appears in the eighth-season episode “The One with the Baby Shower.” She is a talented singer and guitarist hired to perform at Central Perk while Phoebe is away. When Phoebe returns, she discovers that Stephanie has taken over her musical spot and performs “Smelly Cat” with greater technical skill.

Phoebe initially feels threatened, but the two musicians eventually perform the song together. Stephanie is played by singer-songwriter Chrissie Hynde of the Pretenders. This detail is sometimes confused with Phoebe’s later performance of “Smelly Cat” with a professional recording vocalist in the music-video storyline.
