I got it from a friend of my neighbor's cousin's former girlfriend who overheard a conversation at the Burg discussing a surprise celebrity race this Saturday. Supposedly the conversation went something to this effect:

Official 1: Yeah it's going to be huge, we got Stewart.

Official 2: Tony Stewart?

Official 1: No, Ephram Stewart the pickle eating champ from Cincy.

Official 2: Who else is coming?

Official 1: We got Gordon?

Official 2: Jeff Gordon?

Official 1: No, Melvin Gordon he's the local guy that once met Andy Griffith.

Official 2: Oh, who else.

Official 1: Well I don't want to brag, but we got Waltrip.

Official 2: Michael Waltrip?

Official 1: Yep!
