Kramer meets Uma Thurman and writes her phone number on Jerry's dry cleaning ticket.
Because Willie's wife Donna is out wearing the fur coat, he demands Jerry show him the ticket, which Kramer still has.
He passes over attractive women so he can concentrate on his work, and hires Ada, who is very efficient and plain-looking.
Kramer refuses to trade back, so Jerry agrees to buy Bania two meals in exchange for the ticket, but both the dry cleaning number and Uma Thurman's phone number have been erased by the moisturizer.
Elaine is forced to buy the dress because the clerk notices road salt on it and realizes she wore it outside the store.
Bania tells Jerry that he wrote down the telephone number from the ticket before it was washed out and got a date with Uma.
