John H. Schnatter (also known as Papa John) is the owner, founder, and CEO of the real-world pizza chain Papa John's Pizza.
He is mentioned in "Grampu Gets Killed by ISIS" when Oobi's on the phone and Uma asks him if Papa John is calling. From the way they talk about it, it seems like they know Papa John personally.
- Along with Desiigner and Brendan Fraser, he is one of the few real-world people to have a role in the Edgy Oobi universe.
- "Shut the hell up, Uma! I think it's Papa John's!" (quote from Oobi in episode 3)
