muffin tops lineage theory
larry david saw them in a nyc bakery & was both appalled & amused. Basically, he was bemused. since he was always looking for seinfeld script ideas, he then incorporated the muffins tops into an episode.
years later, the damn muffin tops are everywhere, including just about any 7-11 convenience store if you can believe it. & they are the same price as the whole muffins!
...only in America...
or did you mean "muffin tops" as in low-cut jeans?
