It seems every few years someone has topped this record again, but if you think hamburgers are an American specialty, then you'll be happy to know the U.S. reclaimed the title from the Canadians recently. The burger is 777 pounds and contains 590 pounds of beef. Obesity epidemic, eat your heart out...wait.

This stunt was probably a bit wasteful but I personally think no amount of internet snark is going to ever stop people from all parts of the world from trying to break records so if you ever have an opportunity to eat the worlds largest something you might as well do it.
Oh and in case you are wondering the burger tasted more like so so meatloaf than a burger and the bun was quite dense and gross.
i still stand by my statement that stunts like these seem to have no real redeeming qualities. i guess they're not quite as bad as the "eat a 5lb steak in an hour and it's free!" type restaurant contests: with stuff like that, they're not legally allowed to donate any leftovers for health reasons (and the thought of trying to polish off several pounds of food in a relatively short amount of time just sounds super-nauseating, no matter what kind of food it is!)
Anyway, I don't think this big ol'burger would be in very good shape by the time it was shipped to Africa.
