A guy walks into a bar in Oakland and sees that they've got the Raiders game on. He takes a seat at the bar and watches the game for a while. After a bit, the Raiders kick a field goal. As the ball sails through the uprights, the bar owner's dog jumps up onto the bar and does a back flip. Amazed, the guy asks the bartender "How did you train him to do that?" to which the bartender responds "I didn't. He's a stray that was hanging around in front of the bar. We took him in. We had the Raiders game on one day, the Raiders kick a field goal, and he jumps up on the bar and does a back flip." The guy, still amazed, asks "Well, what does he do when the Raiders score a touchdown?". The bartender replies "I don't know, I've only had him for about a year."
