Andy Richter Controls the Universe Season 2 Episode 10

Byron makes use of Andy's sarcastic suggestion of introducing a cartoon character into their deep fryer manual, which instantly becomes a huge hit. Not only does Andy resent Byron for stealing his idea, the 'Duh Dog' is also obviously modeled on him. Meanwhile, Keith has become addicted to the deep fryer in question, frying everything he can get his hands on before devouring it.
