American math teacher and competitive eater Michelle Lesco just broke a Guinness World Record for consuming the most mayonnaise in three minutes - a whopping 2,448 grams of mayo.
That's equivalent to three and a half large jars!
It's also not the only Guinness World Record she holds. She also has the award for the fastest time to eat a bowl of pasta at 26.69 seconds, and the fastest time to eat a hot dog with no hands at 21.60 seconds.
Michelle first got involved with speed-eating after her male friends backed out of eating a burger with 12 patties, 12 cheese slices, lettuce, and tomato. But she took it on without fear and was soon hooked after that.
Why she decided that eating a lot of mayonnaise was a great idea we're not sure... But congrats Michelle!
