A guy and his dog walk into a bar in Dallas on a Sunday. The bartender looks at the two and says "No pets allowed, sir, you'll have to leave" The guy looks desperately at the bartender and says "Please, I'm from out of town, the tv at my hotel is broken, and we're both die-hard Cowboys fans. If the dog makes trouble, we'll both leave no questions asked, I promise. Just let us stay for the game."
The bartender allows it, and the Cowboys end up winning the game. The dog does a somersault and starts shaking hands with everyone wearing a Cowboys jersey. Stunned, the bartender asks "If he gets this excited over the regular season, what does he do when they win in the playoffs?" The guys looks sadly at the bartender and says "I don't know, I've only had him for 9 years..."
