This is the second in a long-running gag of Harry going to a restaurant across the street only to find that it has been completely redecorated overnight and is serving a new cuisine.

In the hospital, Harry is shown reading "The Maltese Falcon." The 1941 John Huston film of "The Maltese Falcon" and "Night Court" were both filmed on Warner Brothers Studio 9.
