A man walks into a bar and orders a 10 year old scotch. The bartender, believing that the customer will not be able to tell the difference, pours him a shot of the cheap 2 year old house scotch that has been poured into an empty bottle of the good stuff.

The man takes a sip and spits the scotch out on the bar and reams the bartender. This is the cheapest 2 year old scotch you can buy. I’m not paying for it. Now, give me a good 10 year old scotch.

The bartender, now feeling a bit of a challenge, pours him a scotch of much better quality, 5 year-old scotch. The man takes a sip and spits it out on the bar. This is only 5 year old scotch. I won’t pay for this, and I insist on, a good, 10 year old scotch.

The bartender finally relents and serves the man his best quality, 10 year-old scotch.

An old drunk from the end of the bar, who has witnessed the entire episode, walks down to the finicky scotch drinker and sets a glass down in front of him and asks, What do you think of this?

The scotch expert takes a sip, and in disgust, violently spits out the liquid yelling Why, this tastes like piss,

The old drunk replies, That’s right, now tell me how old I am.
