Muddy Grimes is the primary antagonist of Beavis and Butt-head Do America.
He first appears when speaking on the phone to a friend of his to send hitmen at Dallas Grimes to steal the X-5 Unit and murder her making it look like an accident. While speaking on the phone, he finds Beavis and Butt-head outside and mistakes them for the men he is hiring. As to using slang, Muddy tells them to "do" his wife, even though the two mistake this as to meaning sexual intercourse. After telling them the rewards and giving them a picture, they give into the adventure.
Later on though, Muddy finds out that he hired the wrong guys and now he must kill them. He finds them out in the desert where they're almost dead from the heat, and then changes his mind to let them live. He takes the two in his trunk so the police will not find them and have himself arrested, as they are on the FBI's Most Wanted list for carrying the X-5 Unit.
When Muddy makes it to Washington D.C., but then he finds out that Beavis and Butt-head escaped from his trunk and he threatens to kill them, until Dallas seduces him by saying that they'll both kill them. Dallas eventually betrays Muddy when they are both arrested when Muddy says that he and his wife were getting together again. They go back to hating each other, and the last seen of them is when they're arrested in a secured truck, along with Tom Anderson.
- Muddy is quite similar to the character Todd Ianuzzi, as both are criminals and intimidate and threaten people younger than they are.
- His name is a pun on "muddy grime".
