Wormicidal whisky

Give me a shot of bourbon and a shot of water - said the obviously heavy drinker to the bartender.

When the order was placed before him on the bar the lush pulled a worm from his pocket and dropped it into the glass of water. After watching it swim around for a few seconds the man drew the worm from the water and dropped it into the whisky. It wriggled briefly, then curled up and died.

You see that? said the lush to the bartender.

It proves that if you keep on drinking whisky you will never have worms.

Man is not a rational animal, but only a rationalizing one; and that is more dangerous than just to be irrational.
