Hardware Jungle

Richie buys tickets to a rock and roll show from Fonzie but has to work at the hardware store when Howard needs to have his tonsils removed. Because he'll be working until 9:00 PM, he won't be able to go to the show, so he asks Fonzie for a refund. Later, Howard tells Richie that he can close the store at 5:00 PM leaving him free to go to the show. He, now, has to ask Fonzie for the tickets back.
