Role in episode
At the Trusty Slab, he wants to order a number 3 with cheese, but he cannot decide. By doing this, he holds up the line and annoys the cashier with his stupidity. Seeing the hold up, Mr. Slabs asks what is going on and Mr. Manward compares their idiotic customer to JimBob.
With this, Mr. Slabs subsequently takes his money and tells him what his order is. He is upset and says that is what he was trying to order. He tries to repeat the order but is unable to. Seeing him, Patrick Star himself ironically remarks on his idiocy and laughs at it.
Mr. Manward tells him, "Don't you have somewhere else to be a nit-wit?" to which he replies, "Not until 4." This is a reference to the episode "I Had an Accident," wherein a similar exchange occurs between Patrick and Sandy.
