A guy walks into a bar and rudely demands a shot of 12-yr old scotch. The bartender thinks, \'this guy doesn\'t 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 doesn\'t 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 mishter, tashte this!\' The patron obliges...he promptly spits it out. \'It tastes like urine,\' he shoots back at the drunk. The drunk replies: \'It ish. How old am I?\'
