||The title of this article is a conjecture.
Though the topic is found within The Simpsons universe, a proper name is not available.
Krusty's agent is the former agent and friend of Krusty the Clown.
After being dropped from Channel 6, Krusty comes to him, his friend and agent, to get help. His agent then drops Krusty as a friend so it is easier to drop him as a client. To prove this, he removes Krusty from his contacts in his phone. He then shuts the door on Krusty's foot as he crawls out the room but doesn't allow him to get it free easily as the button only shuts the door. He then turns his back on Krusty.
He has Gabbo and Arnie Pye on his contacts list, suggesting he is also their agent too.
