A Packers fan walks into a bar with his dog.
The bartender says, “Hey bud, no pets allowed in here.”
The man says, “But wait! This is a special dog, you have to turn on the game to see. When the Packers score, my dog does flips!”
Sure enough, when the bartender turns on the game, the Packers make a few field goals and the dog starts flipping and jumping after each kick.
“Wow,” said the bartender, amazed, “that’s great! What does he do when they score a touchdown?”
“I don’t know, I’ve only had him for three years.”
