Mario

Sure, the game was called Super Mario Brothers, but Mario wasn’t Luigi and Mario’s last name.
What was their last name?
I have no idea. And it’s not on WikiPedia, either.
Maybe Mario’s like Madonna and Cher and has only one last name?
I wonder if he can sing like Madonna and Cher.
According to WikiPedia, he’s held parties, and there’s usually singing at those, right?
Or are those political parties? Are the Mario Brothers like the Kennedy Brothers?
Which one’s the drunk? Which one’s the womanizer?
And which one drove his go kart off the bridge?
Vote for Mario!
