A guy runs into a bar, rebounds, then tries it again. The bartender, a relic from the Alaskan gold-mining days, was curious as to the man's antics, and asks the man his name. "Singletary!" he yells before running into the bar again.
What the heck are you doing, lad, running into my bar like that? You'll knock it down, you will!
"I'm Samurai!" the guy replied, and hit it again, moving it a good two feet off center.
"You're daft!" said the barman, after steadying himself. "Get the hell out of my bar!"
"Why should I?" shouted the guy. "Your sign says '49ers Welcome!'"
(ummm if you need this joke explained, you're not an American football fan..., but here's a big hint:
