Um… Eeeeew.

Wow. Gross.

Brad Sciullo of Uniontown, Pa., is seen before attempting to eat a 15-pound cheese burger with five pounds of toppings including bun, lettuce, tomatoes, cheese, onions, mild banana peppers, and a cup each of ketchup, mustard, relish, and mayonnaise at Denny’s Beer Barrel Pub in Clearfield, Pa., on Monday, Oct. 13, 2008. Sciullo finished the concoction in 4 hours and 39 minutes.

1 cup of mayonnaise?!

Gack.And this one is even worse:

Pa. man chews through belly-busting, 15-lb. burger

AP – CLEARFIELD, Pa. – It took Brad Sciullo 4 hours and 39 minutes to finish a marathon. A meat marathon, that is. The 5-foot-11, 180-pound western Pennsylvania chef is the first person to eat a monstrosity called the Beer Barrel Belly Bruiser: a 15-pound burger with toppings and a bun that brought the total weight to 20.2 pounds.

The mountain of beef is the product of Denny’s Beer Barrel Pub, about 100 miles northeast of Pittsburgh in Clearfield.

Sciullo, 21, of Uniontown, said he was surprised he finished the sandwich Monday. “About three hours into it, things got tough,” he said.

When asked what possessed him to eat a burger that big, Sciullo said: “I wanted to see if I could.”

The burger included a bun, lettuce, tomatoes, cheese, onions, mild banana peppers and a cup each of mayonnaise, ketchup, mustard and relish, pub owner Dennis Liegey said.

For completing the challenge in the under-five-hour time limit, Sciullo won $400, three T-shirts, a certificate “and a burger hangover, as I call it,” Liegey said.
