Don Castellaneta is the boss of the rival family of Fat Tony.
While having a meeting with his own Mafia and Fat Tony's at Luigi's, Don Castellaneta is about to endure in a gun fight. Maggie Simpson is traveling under everyone while Fat Tony's men drop their glasses and have to go to the rest room to 'Clean Up'. When they come out with guns, Don Castellaneta drops his fork and comments, "Clumsy me! I dropped my fork! Boys..." All of his men repeat, Clumsy us! We dropped our forks!," and they hid guns under the table. Then Moe comes in, finds Maggie, and holds her up to the Mafia men, who stop fighting.
