There was a place accross Boones Ferry Rd. from the Albertson's in Lake Oswego, Oregon called the Giant Drive In.
They had a burger called the Super Giant Filler.
Two beef patties, (1/2 lb) slice of ham, fried egg, bacon, slice of pineapple, onions, tomato, lettuce, 2 kinds of cheese,... other stuff I can't remember (its been 10 years) the thing was about 10 inches tall as you detached your mandible to take a bite.
