Continuity mistake: When Kris gives the children toys, one of them says, "What about the Misterburger?" Kris than says, "What about him? I'll save him a big red yo-yo!" and pulls out a red yo-yo. However, when he hands it to the Misterburger, it is not red, but is yellow and has blue and red stripes.
Continuity mistake: Meisterburger has a cast. Then he is walking without a cast. Then he has a cast again.
