Second coming of Christ through competitive eating
FACT 1: Some religious beliefs include that eating consecrated bread and wine (the eucharist) become the blood and body of Christ through the process of transubstation.
FACT 2: Competitive eaters continue to break records, pushing the limits of the stomach further and further.
PUT IT TOGETHER: Base an eating competition around the eating of the eucharist. Eventually someone will eat enough to not just form a representative part of the body and blood of Christ, but the whole thing.
