S3, E15: When Mr. Needles, the family dog, is diagnosed with a tumor, George informs Max that the veterinarian has recommended that Mr. Needles be euthanized the next day. Max promises God that he will be nice to Carmen for a month if He saves Mr. Needles' life, and he forces his skeptical father to make a deal with God as well. Miraculously, Mr. Needles recovers--but George finds that keeping his bargain with God will be much harder than Max doing so.
