Where's the beef? It's at a Pennsylvania pub that serves the world's biggest burger - weighing in at NINE lip-smacking pounds!

That's no whopper - you can actually get this meat monster for $23.95, load with all the "fixins"...

Two whole tomatoes
A half-head of lettuce
12 slices of American cheese
A full cup of peppers
Two entire onions
Plus, a river a mayonnaise, ketchup, and mustard.

NO ONE has ever finished one.

Ginny's diner here in Louisville has something similar. The hamburger itself is 2lb. It probably weighs 5 or 6 lb. dressed with a bun. The burger is free if you can eat all of it in one sitting.
