Best Michigan Joke Ever

A man dressed in Scarlet and Gray walks into an Ann Arbor sports bar with a small dog under his arm. He says to the bartender.

"Hey, can I leave my dog here while I go to the OSU - U of M game?"

"A dog in my bar? No way."

"But he's a special dog," the OSU fan says.

"In what way?" The bartender asks.

"Well," says the Buckeye, "he will watch the game on TV with you. When OSU scores, he will walk up and down the bar on his hind legs. When Michigan scores, he will walk up and down the bar on his front legs. When Ohio State wins, he will do back flips all the way down the bar and back."

"Wow," the bartender says. "What does he do when Michigan wins?"

"I don't know" says the Buckeye. "He's only seven years old."
