A competitive eater who goes by the name Katina Eats Kilos has gone viral after eating a 72-ounce steak.  She did it at the Big Texan Steak Ranch in Amarillo, Texas . . . and you get the whole meal free if you can do it in under an hour.

She had to polish off the steak, plus a baked potato, side salad, roll, and some shrimp . . . and she did it in 40 minutes and 35 seconds.  She says it was for the experience, not to set a record.
