The Iowa fan and his dog...
There's a fellow visiting his friend in Iowa and a Hawkeye game is on TV. Iowa kicks a field goal and his dog does a backflip, howls and dances around on his hind legs in a circle. As you can imagine, the visitor is pretty impressed. Then about a half hour later Iowa kicks another field goal and the dog once again does a backflip, howls and dances in a circle. The visitor says to his Iowa buddy, "Wow! That's a pretty neat dog. Tell me, what does he do when they score a touchdown?" The Iowa guy replies, "I'm not sure, I've only had him for four years."
