The Big Texan restaurant in Amarillo, Tex., has something called the “72oz Steak Rules“: If a customer can consume a steak that size in an hour, plus sides consisting of a shrimp cocktail, baked potato, salad and a roll with butter, without getting up from the table or receiving any help, he or she gets the $72 charge refunded.

Turns out, quite a few folks have brought a Texas-sized appetite into the place and accomplished that feat, including some competitive eaters. Joey Chestnut, the reigning king of competitive eating, had held the crown for fastest time, but a relatively slight woman named Molly Schuyler demolished it last year, polishing off the entire meal in under five minutes.

Then she immediately started on another 72-ouncer, but Schuyler, a 34-year-old mother of four, took her time with this one, completing the meal in just under 10 minutes. “If there’s a zombie apocalypse, I want to stay away from this girl,” restaurant owner Danny Lee told the Amarillo Globe-News.

However, that was in 2014, and this year, The Big Texan upped the stakes. The restaurant offered the 120-pound Schuyler $5,000 if she could come back on Sunday and take down three of the 72-ounce behemoths in under an hour. That’s over 13 pounds in beef alone, plus three portions of all the sides.

Just to make things even more interesting, the restaurant offered $1,000 to some other eaters. They were grouped into four teams of two, what with being mere mortals and all, although some teams included football players, among them former NFL quarterback Keith Null.

Schuyler didn’t just wipe out the competition, she wolfed down all 216 ounces of steak, and all the shrimp cocktails, baked potatoes, rolls and salads, in a ridiculously short amount of time. First, Schuyler broke her own record for a single serving of the gargantuan meal.

And then the rest of the dominoes fell, with outrageous speed.

20 minutes. That’s simply astounding (and a little nauseating).

“We’ve been doing this contest since 1960, and in all that time we’ve never had anybody come in to actually eat that many steaks at one time — so this is a first for us and after 55 years of it, it’s a big deal,” Lee told the local ABC News affiliate.
