Question: Are "Happy Tarts" an actual product in America? They're displayed throughout the film as an obvious product placement joke, but is it a product made up for the benefit of the joke, or did the film makers make a real product placement into a joke?
Chosen answer: No, Happy Tarts is not a real product (unless you live in South Park where Cartman sometimes has them along with Cheesy Poofs and Snacky Cakes).
Answer: He meant he didn't want him visibly messed up, i.e. no bruises, cuts, or breaks.
