I guess they didn't get the memo on obesity

A minor league baseball park in Grand Rapids, Michigan has added a major league item to its menu--an unbelievable four pound burger! The monstrosity contains 4,800 calories and it's price tag is also major league--it'll set you back $20. But they say that anyone who eats it all in one sitting will receive a special T-shirt. Mama mia! Atsa one big hamburger!
