We used to get the deluxe breakfast when I was a kid - they weren't very deluxe as far as size considering the calorie/fat count. I didn't think they still made them.
The worst I've had recently is McD's double cheeseburger. And I can tear up fries from pretty much anywhere, although I've decreased my fast food intake to about once every month or two. I've never had any of the above. A small DQ Blizzard is barely do-able, I can't imagine downing a large. And I can eat.
