A Drinking Problem
 
   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 in turn. 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 an
   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, then a light dawns in his eye
   and he laughs.
   "Oh, no," he says, "everyone's fine. I've just quit drinking."
