“12 Year Old Scotch
A man walks into a bar and asks the bartender for twelve-year-old scotch. The bartender thinks “”This guy is pretty pretentious”” and proceeds to pour him a drink of six-year-old scotch.
He gives it to the customer who takes a drink, exclaiming, “”This isn’t twelve-year-old scotch, this is six-year-old scotch”” The bartender thinks, hey this guy knows what he’s talking about, and the two of them get into a conversation about where the customer is from etc..
At one point an old guy, who was sitting at the other end of the bar comes over with a glass and hands it to the customer. The latter takes a drink, and spits it out. “”This is piss!”” he yells. The old guy nods and says,
“”Yeah, but how old am I?””
