A guy walks into a bar and rudely demands a shot of 12-yr old scotch.

The bartender thinks This guy doesnt know the difference, so he pours a shot of 2-year old scotch.

The patron takes one sip and spits it out.

He promptly hollers at the bartender: I said 12-year old scotch, you bozo!

Still unimpressed the bartender pours some 6-year old scotch.

The patron takes a sip…same reaction. But the bartender still doesnt believe the patron knows the difference. So he pours a shot of 10-year old scotch. Again, same reaction from the patron.

Finally, the bartender is convinced. He pours the patron a glass of 12-year-old scotch. The patron takes a sip and is most satisfied.

All the while this has been going on, a drunk at the end of the bar has been watching. He slides a shot glass down the bar to the patron and drunkenly says: Shay mister, taste this! The patron obliges…he promptly spits it out.

It tastes like piss, he shoots back at the drunk. The drunk replies: It is. How old am I?
