In a revelation that has left fans baffled and historians exhausted, researchers at the University of Obvious, Ohio, announced this week that American football can trace its roots back to 13th-century England, where peasants in full plate armor spent Sunday afternoons tackling each other for possession of a disturbingly large pig bladder.

“It really opens your eyes,” said sports historian Dr. Linda Farsworth, who recently completed a 900-page report titled ‘First Down in Feudalism.’ “Medieval villagers would form two teams of 53, then spend hours trying to carry a misshapen lump of animal product into the local moat, all while being screamed at by a man who looked suspiciously like Bill Belichick.”

The revelation has caused an identity crisis among NFL enthusiasts. “I always thought football was as American as apple pie and mild traumatic brain injury,” confessed Packers fan Walt Dorgen, who is now switching his game-day outfit from a cheesehead to a chainmail hood.

British Prime Minister Sir Neville Twigsby issued a statement demanding credit for inventing America’s game: “It was all us, mate. Your touchdowns are just medieval goals, but with more commercials for insurance. You’re welcome.”

NFL officials are reportedly considering new rules for the 2024 season, including mandatory jousting at halftime and replacing the coin toss with the flinging of a turnip. “If it honors our savage, mud-splattered heritage, I’m all for it,” said Commissioner Roger Goodell, moments before declaring ‘ye olde instant replay’ mandatory for all disputed calls.
