The Irishman

                                      
        An Irishman walks into a bar in Dublin, orders
   three pints of Guinness and sits in the back of the room, drinking a
   sip out of each one inturn.  When he finishes them, he comes back to
   the bar and  orders three more.
   The bartender asks him, "You know, a pint goes
   flat after I draw it; it would taste better if you bought one at a
   time."
   The Irishman replies, "Well, you see, I have
   two brothers. One is in America, the other in Australia,
   and I'm here in Dublin.  When we all left home, we promised that 
   we'd drink this way
   to remember the days when we drank together."
   The bartender admits that this is a nice custom,
   and leaves it there.  The Irishman becomes a regular in the bar, and
   always drinks the same way: He orders three pints and drinks them in
   turn.
    One day, he comes in and orders two pints. All
   the other regulars notice and fall silent.
    When he comes back to the bar for the second
   round, the bartender says, "I don't want to intrude on your grief, but
   I wanted to offer my condolences on your great loss."
   The Irishman looks confused for a moment, the a
   light dawns in his eye and he laughs. "Oh, no," he, says, "everyone's
   fine.  I've just quit drinking."
