Buffalo chicken wings
If you watch football regularly, there's a good chance that you’ve consumed some sort of chicken wing. Probably within the last week. But until an erroneous chicken delivery to the Anchor Bar in Buffalo, New York, the wing was considered about as useful a part of the bird as the foot.
Yes, according to the Smithsonian (because it’s THAT much a part of American history), in 1964 a chicken purveyor incorrectly delivered a bunch of wings instead of chicken necks to Buffalo's Anchor Bar. Co-founder Frank Bellissimo then asked his co-owner/wife Tessa to make some kind of bar app to help get rid of them. She cut the wings in half (drums and wings), deep fried them without breading, covered them in a buttery hot sauce, and served them with celery. An instant hit, within 30 years they were being served at Pizza Hut. But you know this.
