CLEARFIELD, Pa. - Kate Stelnick may weigh only 100 pounds, but her appetite is remarkable.

The college student from Princeton, N.J., is the first to meet a restaurant's challenge by downing its 6-pound hamburger - and 5 pounds of fixins' - within three hours.

Stelnick didn't eat for two days to prepare for the challenge.

"I felt very full, but I was too excited that I actually ate it to notice," Stelnick said.

Stelnick, 19, made the five-hour drive to Denny's Beer Barrel Pub with two friends from The College of New Jersey on Wednesday, after they saw pictures of the monster burger, dubbed the Ye Old 96er.

Denny Leigey Jr., the owner of the bar, had offered a 2-pound burger for years and conceived of the 6-pounder after his daughter went to college and phoned him about a bar that sold a 4-pounder.

But nobody had finished the big burger in the three-hour time limit since it was introduced on Super Bowl Sunday 1998. In addition to the meat, contestants much eat one large onion, two whole tomatoes, one half head of lettuce, 1¼ pounds of cheese, two buns, and a cup each of mayonnaise, ketchup, mustard, relish, banana peppers and some pickles.

Stelnick did it all in two hours, 54 minutes.

Leigey said he was pretty sure somebody would meet his burger challenge, though he didn't have a petite woman in mind.

"I wouldn't have made it if I didn't think it was possible," Leigey said.
