Rate this episode: {extravote 1}

Mario loses his golden plunger after a battle with King Koopa. He tells Princess and Toad that this was a special plunger because it was given to him by the President of the United States. Mario tells them how he and Luigi became plumbers, and how they had to put up with their overly strict boss, Sarjant Kooperman (who ironically sounds a lot like Koopa). Kooperman ended up failing the Mario's who soon found themselves facing their biggest plumbing challenge ever.

After getting a phone call from the U.S. President, the Marios find themselves giving Russian Premier Mikhail Gorbachev a lesson on how to make pizza.
