Goober Burger

Invented in Minnesota, it's basically just a hamburger with peanut butter on it. Also known as a "fat taxi driver with a Polish accent" if you happen to be a Jimmy Neutron fan

Waitress: Hello sir, would you like to try a Goober Burger?
Me: What's in it?
Waitress: Only our finest peanut butter
Me: .............WHAT KIND OF FAST FOOD SORCERY IS THAT!?
