This character model's name has varied; in most appearances from seasons 1 to 10, he was nameless, with the exception of "Patty Hype" in which Tom calls him Fred in a very brief throwaway line. His name was given as Clint in "Big Sister Sam" from season 7. In season 10, the new showrunners re-adopted the name Fred after seeing it on fan-made wikis. They mistakenly believed that Fred was a fan-given name.
In February 2019, Mr. Lawrence said: "Fans started talking about [the 'my leg' gag] and named him Fred." In October 2019, Vincent Waller said, "By that, he means the fans named him and we went, 'That's a good name for him. That'll work.'" Tom Kenny elaborated: "Bask in the power of the internet: the fans named him Fred."
