While we're drinking...

An older gentleman walks into a bar and orders a 18 year old scotch.  The bartender pours him a shot, and hands it to the man.  He takes one sip and spits it out, yelling "This is 5 year old scotch, I ordered 18!"  So the bartender pours him another shot.  Handing it to the man, he takes a sip and yells "This is 15 year old, I want 18!"  Getting frustrated, the bartender descretely urinates into a shot glass and hands it to the man.  He takes a sip and exclaims, "This tastes like P*SS!"  To which the bartender replies, "Yeah, now tell me how old I am!"
