Two Russian sailors decide to quit drinking,
but they still have a bottle of vodka left, and they refuse to let it go to waste, so one says:" Anatoli, i shall hold the bottle in one hand behind my back, if you can guess which one, we will drink it, if not, i will throw it overboard." They agree on this. The first sailor hides the bottle, the second guesses:"Left!"
"Keep guessing, Anatoli, keep guessing."
