The bartender finally relented, and served the man his best quality twelve-year-old scotch.
The entire episode had been witnessed by an old drunk at the other end of the bar. He now walked up to the selective scotch drinker, put a glass down in front of him and asked: “What do you think of this?”
The scotch expert took a sip of the golden liquid and spat it out violently on the bar. “That’s disgusting!” he said. “It tastes like piss!”
“It is,” replied the old drunk. “Now tell me how old I am.”
