A man walked into a bar and sat down for a drink. He noted a dog intently watching a Cowboys-Redskins game. Whenever the Redskins scored, the dog would jump onto the bar and do an animated dance. This happened over and over as the Redskins scored again and again. At the end of the game, the dog let out a loud howl and ran out of the bar. The man couldn’t believe his eyes.
“That’s amazing,” he told the bartender. “What happens when the Cowboys win?”
“I don’t know,” said the bartender, “The dog’s only four years old.”
