|Picture of Ernie Sabella, who was to play Mo Korn|
|Portrayed by||Ernie Sabella|
Mo Korn was a gun dealer, who was set to appear in the un-produced episode, The Bet. He was described in the script as "overweight, greasy, slow and low-key". Elaine was supposed to go see him to buy a gun as part of a bet with Jerry. Ernie Sabella was cast to play Mo, but the episode was never made, and he never re-appeared.
