A man walks into a bar and orders a 12-year-old scotch.
 
 The bartender, believing that the customer will not be able to
 tell the difference, pours him a shot of the cheap 3-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 3-year-old scotch you can
 buy. I'm not paying for it. Now, give me a good 12-year-old
 scotch."
 
 The bartender, now feeling a bit of a challenge, pours him a
 scotch of much better quality, 6-year-old scotch.
 
 The man takes a sip and spits it out on the bar. "This is only
 6-year-old scotch. I won't pay for this, and I insist on, a good,
 12-year-old scotch."
 
 The bartender finally relents and serves the man his best quality,
 12-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."
