The bar tender tells him his dog has to leave, but the man assures him the dog is well trained and is the biggest fan he'll ever meet.
Sure enough, the dog sits quietly watching the game until in the 2nd Quarter, Utah gets a field goal, and the dog runs up and down the bar high fiving the other fans and does a back flip off the end of the bar.
"Wow!" The bartender exclaims, "That's amazing! What does he do for a touchdown!?"
"I don't know," the man responds, "I've only had him 3 years."
