A Tennessee grad, an LSU grad, and an Alabama grad are riding across the rural South when their car suddenly breaks down. After some initial trepidation, they see a farmhouse off in the distance. Upon arrival, the farmer and his wife greet them and tell them they are welcome to spend the night, as no mechanic is available in the small town at that hour. "There's only one problem," says the farmer. "One of you is going to have to sleep in the barn with my prize pig and my favorite cow." The Tennessee grad says he grew up on a farm and that shouldn't be a problem. He heads to the barn. 30 minutes later, there's a knock at the door. The UT grad tells everyone, "I'm sorry, the smell of the pig is too much for me." The LSU grad says that's no problem, his grandfather raised hogs. 15 minutes later, there's a knock at the door. The LSU grad announces that he just can't handle the smell of cow dung. The Alabama grad says, "Not to worry, I'm so tired I won't notice the smell." 5 minutes later there's a great racket at the door. It's the pig and the cow.
