Plot
Because Elaine wrote a good piece on Himalayan Walking Shoes for the J. Peterman catalog, Peterman is taking her out for dinner. She finds his stories boring, so she pleads with Jerry to join her. He, in turn, tricks George into coming. George and Susan fight after George refuses to tell her his ATM code.
Elaine does not appear at the dinner, on account of a date with Fred, a friend of Jerry. Elaine met him at a party, but his lack of recall of the meeting mesmerizes her. After it becomes clear that Elaine is not coming, Jerry makes up an excuse to leave, leaving George to have an awkward dinner with Peterman. On the drive home, Peterman receives a call that his mother is "at death's door", and George is forced to stay the night. While Peterman is out of the room, George, whilst keeping her company, reveals his code ("Bosco") to Peterman's mother. She seizes upon the word, and repeats it at her moment of death, leaving Peterman bewildered.
Jerry meets with appliance store owner, Leapin' Larry, who has a prosthetic leg, to discuss appearing in television commercials. After Jerry's foot falls asleep, he offends Leapin' Larry, who believes Jerry's limping to be an impression. After Jerry explains the misunderstanding, they meet again, but Jerry's foot again falls asleep. Not wanting to offend Leapin' Larry again, he stamps his foot, accidentally causing a can of paint thinner to spill onto some exposed wiring, starting a fire.
