Shaggy and Scooby compete against real-life celebrity comedian Jim Gaffigan (because Andy Richter was busy that day) in a fast-food themed race.

Memorable quotes
Scooby: Raggy, look! Shaggy: Not him! Gaffigan: Ahhh! Yes, dudes, it's me... In all my paleness. Fred: Wow! It's... Fred, Velma, and Daphne: Actor-writer-producer and stand-up comedian Jim Gaffigan!

Shaggy: Like, Scoob, my mouth is watering just thinking about that 70-year-old burger! Scooby: Yeah, me, too! Gaffigan: Well, don't get your mouths too watery, cos I'm gonna be the one eating that 70-year-old burger, and I'm gonna eat it right in front of you and those meddling kids.

Bill: And I would've gotten my revenge, too, if it weren't for you meddling kids and that comedy legend Jim Gaffigan.
