A guy walks into a restaurant with a dachshund under his arm. The dog is wearing a Detroit Lions jersey and helmet, and is festooned with Lions pom-poms.

The waiter says, "Hey! No pets are allowed! You'll have to leave."

The guy  begs him, "Look, I'm desperate! We're both big fans, the TV's broken at home, 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 waiter relents and allows them to stay in the restaurant and watch the game.

The big game begins with the Lions receiving the kickoff. They march down field and score a touchdown. Suddenly, the dog jumps up and begins walking up and down the aisle giving high-fives to everyone.

The waiter says, "Wow, that is the most amazing thing I've seen! What does the dog do if they win?" The owner replies, "I don't know, I've only had him for three years."
