When Mario breaks Luigi's Nintendo 64, Mario must find a replacement or its his head.
When Mario finds Luigi playing Super Smash Brothers on his N64, Mario insists he plays Brawl on the Wii. Luigi says it is a classic game, but Mario asks if it has Smash Balls, more characters and fun. Mario says he sucks at Smash and the screen is too small. Luigi then insults Mario, and Mario asks if he can play. While Luigi gets another controller, Mario tilts the cartridge. The 64 then breaks, while Luigi returns. Mario tries to find a way out of the situation, and Luigi tells Mario to buy him a new 64. Mario says they don't sell them anymore, but Luigi denies.
As he leaves the castle he complains about that stupid console being so 1990s. He asks Toad if he has a 64, but Toad insists he gets an Xbox 360. He asks Bowser because he looks old, he says no. Mario thinks about eBay, but he remembers that they always scam him. Mario asks the wall, and Lakitu asks why. He tells a penguin if it doesn't have a 64, he will kill its baby. But his hand slips and drops the baby. He asks Peach, who has a SNES instead, and throws her into the air, complaining about how old she is. He asks a clone of himself, but the clone says he needs to find an N64 for his brother.
Toad tells Mario that Nintendo might have one left. Toad says it's probably in Japan but there might be another way there. Mario asks God, and God says there is a pipe in the castle that will take him to Nintendo. Mario goes through the pipe, Mario arrives at Nintendo, which is covered with the Nintendo logo, and says it looks like Peach's Castle. Mario asks the receptionist if he can meet with the boss. He asks the boss, and yet again, Mario is insulted. The boss says he has no 64s, they sold all 1033357245331455627322463442373235636462315 of them. He tells him to get out, and Mario takes out a Bob-omb and explodes Nintendo.
He returns to the castle, and Toad tells him they wouldn't exist without Nintendo. It is revealed he went back to 1990 to get one. Luigi is playing Mario 64, but Mario says it sucks and thinks it would be fun to make movies about it. Lakitu sighs. Mario then has a GameShark, and puts it into the 64. The 64 breaks again.
