Holy shit! My wife and I just saw that episode on Food Network. We both laughed our asses off when we saw that thing and now someone has actually eaten it!
If anyone else saw that special, there was another burger joint, in Nashville, called Fat Mo's. They have a 27 oz. burger called the Super Deluxe which I thought was gigantic (until now). My friends and I each ordered one at lunch one day and we all finished them. I felt so sick the rest of the day, I can't imagine how this girl got that all down.
