"Good afternoon, my good barkeep, a pint of Less if you please," said the old man as he entered the tavern.
"Less? Never heard of it," replied the barman.
"Oh, come now surely you have," he persisted.
"No sorry, we certainly don't stock it. What is it anyway? Some foreign beer?"
"Well I'm not sure," admitted the man. "It was my doctor who mentioned it. He said I should drink less."
If four or five guys tell you that you're drunk, even though you know you haven't had a thing to drink, the least you can do is to lie down a little while.
~Joseph Schenck
