In the first episode of "The Keys," -- Jerry takes his keys back, Kramer heads for LA -- Jerry brings a date home to find Kramer has already let himself in and is entertaining a girl of his own. It's this woman who appears again in the episode where Jerry leaves a stain on the Costanza's coffee table (and Elaine meets Ricky, the TV Guide fetish guy). She's the female employee of the furniture refinisher -- the one George brings back to his parent's home.
