Episode 31-Mario Moves In

Mario Moves In is the 31st episode of the series and the first episode of Season 4.

Plot
Luigi opens the episode saying he has a gun, but Mario tells him it's just a hockey stick. Luigi says he is going to take a bath offscreen, and Mario is disgusted for some reason and runs off to Herp-A-Derp's house. Herp-A-Derp & Herp-A-Derp Stuntman are bored and have nothing to do, so Mario appears and asks if he can stay at Herp-A-Derp's for the night. Herp-A-Derp asks why, and Mario says it's because Luigi's taking a bath. He asks whats so wrong about that but then he hears Luigi's "song" and says it's terrible and he can stay to his dismay. After a conversation with Luma, Herp-A-Derp and Mario try to look at Playboy, but they instead get Herp-A-Derp Stuntman. Herp-A-Derp then fires him for the episode. After several random moments involving side characters, they decide to eat pretzels and watch BrainSurge. After trying to guess the answers to the questions and being scared by closeups, they then decide to go to sleep. The next morning Mario thanks Herp-A-Derp for letting him come over but he says they still have one more thing to do and they go to a strip club offscreen. Luigi then appears naked with a tissue covering his crotch and is attacked by Mario.
