[1] In this episode, Jerry jeopardizes his chances of becoming a member of the New York Friars' Club when he accidentally takes a club jacket home with him, George hopes to spend more time with Jerry by fixing him up with his fiancé Susan's best friend, and J. Peterman saddles Elaine with the workload of her hard-of-hearing co-worker.
Jerry is unable to return it before a second double date, this time at the Flying Sandos Brothers magic show.
Elaine is pressured to attend by her boss, who suspects her remarks to Bob were not sincere and she was making fun of his handicap (which would ultimately result in her being terminated from her job).
Jerry is told he owes $800 and will no longer be under consideration for Friars Club membership if he fails to return the jacket.
Hallie witnesses this just before returning the real Friars Club jacket to Jerry, and loses interest in their double dating.
The magicians chase Jerry and George backstage to recover their jacket, through the emergency exit, which sounds the alarm.
Due to the dangerous nature of the stunt, Michael Richards was given a small oxygen mask which he concealed inside his clothes, and two professional scuba divers were present in the tank.
[3] The script for "The Friar's Club" was extremely long even by Seinfeld standards, so numerous sequences had to be removed during editing.
