On, Wisconsin!

A guy walks into a Wisconsin bar with a dachshund under his arm.
The dog is wearing an Iowa football jersey and helmet, and is festooned
with Iowa pom-poms.

The bartender 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 bartender relents and allows them to stay in the bar
and watch the game.

The big game begins with Iowa receiving the kickoff. They
march down field, get stopped at the 30, and kick a field goal.
Suddenly, the dog jumps up on the bar and begins walking up and
down the bar giving high-fives to everyone.

The bartender says, "Wow, that's the most amazing thing I've ever
seen! What does the dog do if they score a touchdown?"

The owner replies,

"I don't know, I've only had him for three years."
