Joke for Scotch Lovers

A man walks into a bar and asks the bartender for a glass of 100 year old scotch.

The bartender thinking the guy doesn't know any better grabs a cheap bottle and pours a glass. The man immediately spits it out and says "I told you I wanted 100 year old scotch"

The bartender figures the guy knows a little, and pours a glass of 12 year old scotch. The man takes a sip and spits it out and says "I told you. I want 100 year old scotch, this is only 12 year old scotch.

The bartender realizes the guy knows his stuff, and grabs his finest bottle of 36 year old scotch, thinking there is no way this man knows the difference. The man takes a sip, spits it out and says, "Look, that was 36 year old scotch. I'm going to tell you one last time. 100 year old scotch or nothing."

The bartender realizes he has no choice, and goes into the cellar. He finds an old dusty bottle, brings it up, pours a glass and hands it to the man. He takes a sip and goes "oh man. That is some good 100 year old scotch"

Meanwhile, a drunk at the end of the bar has been watching this whole thing. He walks up to the man with a drink and says "here, try this"

The man spits it out and says "Dear god. That tastes like piss!"

The drunk says, "yeah, but how old am I?"
