We used to live in Memphis (small town in the panhandle, near Childress) in the early 80s, and we'd go to Amarillo on the weekend for entertainment. We ate at the Big Texan a couple of times, and saw the pictures of the people who ate the whole thing. They also had one of the 72 oz "steaks" (looks like a really big roast) on display. I can't believe there is anyone who could eat all that at one sitting, or even several.
Looks like she ate TWO! From Wikipedia:
"Molly holds a similar 2014 record at Amarillo's Big Texan Steak Ranch, polishing off a 72 ounce steak with side dishes in under five minutes and returning for seconds (14 minutes and 53 seconds for both meals.)"
She has a whole list of other unbelievable eating accomplishments.
