In a local restaurant a waitress offered the patron a cup of coffee. He refused, pointed a finger at her and said, "Young lady, don't you know that every single person who drinks coffee dies?"

Flustered, she said, "Really?"

Another customer said, "Hey, Mister. Don't scare the young lady like that. Everyone who does NOT drink coffee dies, too."

"I know," said the first patron. I am studying to be a politician. Half truths, even if what I said is the whole truth, is good enough."
