Sausage for Breakfast?

A good friend just forwarded me an email of a picture someone took of an alleged 1800 pound wild hog, allegedly shot somewhere south of St. Louis. Now I don't claim to know everything about pigs, but I'm guessing the picture of the alleged super hog was photo shopped. My thought process is: if a wild ranging pig was capable of growing to the size of an African Water Buffalo while subsisting on roots, acorns, and an occasional dead shake, don't you think Tyson foods could have by now figured out how to grow a pen raised, corn fed hog to at least twice that size?

If the picture is real, I'm going hog hunting and if successful, we won't have to buy bacon or sausage for at least a month (I eat a lot of bacon and sausage).
