A guy walks into a bar and says to the bartender, "I want you to give me a 12-year scotch, and don't try to fool me because I can tell the difference."
The bartender is skeptical and decides to try to trick the man with 5-year scotch. The man takes a sip, scowls and says, "Bartender, this crap is 5-year scotch. I told you I want 12-year scotch." The bartender tries once more with 8-year scotch. The man takes a sip, grimaces and says, "Bartender, I don't want 8-year scotch like this filth. Give me 12-year scotch!"
Impressed, the bartender gets the 12-year scotch, the man takes a sip and sighs, "Ah, now that's the real thing."
A disgusting, grimy, stinking drunk has been watching all this with great interest. He stumbles over and sets a glass down in front of the man and says, "Hey, I think that's really far out what you can do. Try this one."
The man takes a sip and immediately spits out the liquid and cries, "Yechhh! This stuff tastes like piss!"
The drunk's eyes light up and he says, "Yeah, that's right!, now how old am I?"
