Jerry Seinfeld on "Unfrosted," the made-up origin tale of Pop-Tarts

It started with a stand-up bit, from Jerry Seinfeld's Netflix special, "23 Hours to Kill": "When they invented the Pop-Tart, the back of my head blew right off!"

And like all good comedy, it was based in truth. In 1964, when the Pop-Tart was introduced, 10-year-old Jerry Seinfeld fell hard.

Asked if he had a favorite flavor from the start, Seinfeld replied, "Brown sugar cinnamon, obviously."
