A man walks up to the bar and asks the barkeep for a shot of 40 yr old scotch. The barkeep doesnt want to give up the good stuff, so he gives him a shot of 10 yr old scotch. The man drinks it and then looks at the barkeep and says I asked for a shot of 40 yr old scotch, not 10 yr old scotch. I want a shot of 40 yr old scotch.The barkeep, still unwilling to let the good stuff go, thinks the man just made a lucky guess at the age of the first shot, so he gives him a shot of 30 yr old scotch. The man drinks it and says to the barkeep I asked for 40 yr old scotch, not 30 yr old scotch....I want a shot of 40 yr old scotch. By this this time the man had drawn quite a crowd.The bartender, wondering if the man can really tell how old the scotch is, gives the man the 40 yr old scotch. The man drinks it and says Now that's 40 yr old scotch! Just then, a man yells here, drink this. After drinking it, the man says THIS TASTES LIKE PISS! The other man says YES, NOW TELL ME HOW OLD I AM!
