A guy walks into a bar and announces that he can close his eyes and name what kind of alcohol he is drinking and how old it is, just by taste and smell.A drunken guy at the bar says, "I bet I can give you a drink that you can't name.""You're on," replies the guy, "as long as you pay."So the drunken guy puts a drink on the table. The guy sips it, gags and spits it out. "This tastes like piss!""Yeah," says the drunken guy, "now guess how old I am."
