The first guy is eating a burger from Denny's Beer Barrel Pub in Clearfield, Pennsylvania...It uses 6 lbs of meat.
As advertised on the pub's web site, a 96er sells for $23.95 and includes the following fixings and condiments:
Two whole tomatoes
A half-head of lettuce
12 slices of American cheese
A full cup of peppers
Two entire onions
A river of mayonnaise, ketchup, and mustard
Denny's (not to be confused with the national chain restaurants of the same name) offers prizes for customers who can completely consume one of their big burgers within three hours: a T-shirt, certificate, and 50% discount for anyone who finishes a Challenger (2 lb. burger) within an hour; a T-shirt, certificate, and 100% discount for anyone who can polish off a Baby Boy (3 lb. burger) in 90 minutes or less; and something special for anyone who manages the unthinkable and puts away a whole 96er (6 lb. burger) in under three hours.
The pic I showed... the uncooked burger weighed in at seventeen pounds. The specially baked buns were seven pounds each. The assembled burger weighed 29.75 pounds, with a pound of bacon, two pounds of cheese, grilled onions and portabella mushrooms, avocados, tomatoes, lettuce, mustard, ketchup, and a giant toothpick through the center with deli pickles on top. The buns were baked on a pizza pan with a custom-fitted steel ring around the edge.
