For the sake of not stirring up trouble... I'll use my team,(the Chiefs) for this joke. Even though you can change the team for your least favorite team. And yes I am a Chiefs fan. Hey Schro... I think this really was meant for the Raiders....

This guy walks into a bar wearing a Chiefs jersey and carrying a little
dog that also has a Chiefs jersey on with a little Chief helmet too.
The guy says to the bartender, "Can my dog and I watch the Chiefs game
here? My TV at home broke and my dog and I want to see the game."
The bartender replies, "Normally, dogs in the bar would not be allowed,
but it is not terribly busy in here, so you and the dog can have a seat
at the end of the bar. But, if there is any trouble with you or the dog,
I'll have to ask you to leave."
The guy agrees and he and his dog start watching the game.
Pretty soon the Chiefs kick a field goal and the little dog jumps on
the bar and walks down the bar and gives everyone a high five.
The bartender says, "Hey, that's cool! What does he do for a touch down?"
The guy answers, "I don't know, I've only had him for 3 years."
