We learn a great deal about Phoebe. Her mother worked on a barge and with the jingle girl's mother. Jingle girl was her childhood best friend up until five years ago.
Chandler meets a girl in the men's restroom. Her name is Ginger and as it turns out Joey had an incident involving her wooden leg. He can't really handle the premise of a wooden legged girl friend but he excepts it. When she learns he has a third nipple she freaks out and leaves.
Ross falls asleep at Rachel's fashion lecture that he attends merely to keep Mark away from her. I think this is the beginning of their relationship problems.
In the end Phoebe STUPIDLY gives the jingle girl "Smelly Cat" and she, jingle girl abandons her yet agian, and turns it into a kitty litter jingle. "Go to hell jingle whore..."
