A man walked into an Oakland bar with a dachshund under his arm. The dog was wearing an Oakland Raiders jersey and helmet, and was festooned with Raiders pom-poms.
The bartender said, "Hey! No pets are allowed in here! You'll have to leave!"
The guy begged him: "Look, I'm desperate. We're both big fans, the TV is broken, and this is the only place around where we can see the game!"
After securing a promise that the dog will behave, and warning him that he and the dog will be thrown out if there's any trouble, the bartender relented and allowed them to stay in the bar and watch the game.
The big game began with the Raiders receiving the kickoff. They marched down the field, got stopped at about the 30, and kicked a field goal.
With that the dog jumped up on the bar, and began walking up and down the bar giving high-fives to everyone.
The bartender said, "Wow, that is the most amazing thing I've ever seen! What does the dog do when the Raiders score a touchdown?"
The owner replied, "I don't know, I've only had him for 4 years."
