John Hampton "Papa John" Schnatter (born November 22-23, 1961) is an American entrepreneur, best known for founding the Papa John's chain of pizza restaurants.
In "Fertilized Megg", when the pregnant Meg asks to eat something rank in the middle of the night, Peter heads out to Papa John's mansion, where he spends a few minutes criticizing various aspects of the pizza his business makes, before ordering a bunch of everything on the menu.
When Wild West sees a trail of black hair dye on the floor of an ESPN Zone in "A 'Stache from the Past", he believes it could lead them to Tom Selleck, Papa John or Rudy Giuliani.
