The entire premise of the bad sandwich being named after Larry was an actual event when Larry David and, Ann Frank actor, Michael E. Perry went to an LA deli that had actors names assigned to sandwiches. Perry called the owner of the deli over to their table and said, "This is Larry David. The creator of Seinfeld. You should name a sandwich after him". The deli owner, never having watched Seinfeld, asked a customer what they thought of Seinfeld. The customer assumed he meant the actor not the show and replied, "He's a bad Jew that never goes to temple. He believes Moses fed the Jews picked herring and sable while wandering in the desert." Larry found the exchange funny and wrote it down.
