A man walked into a bar on a slow night and sat down. After a few minutes, the bartender asked him if he wanted a drink.
He replied, “No thanks. I don’t drink. I tried it once, but I didn’t like it.”
So the bartender said, “Well, would you like a cigarette?”
But the man said, “No thanks. I don’t smoke. I tried it once, but I didn’t like it.”
The bartender asked him if he’d like to play a game of pool, and again the man said, “No thanks. I don’t like pool. I tried it once, but I didn’t like it. As a matter of fact, I wouldn’t be here at all, but I’m waiting for my son.”
The bartender said, “Your only son, I’m guessing.”
