Cowboy

 A cowboy walks into a bar in Texas, orders three mugs of
 brew and sits in the back 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 approaches and tells him, "You
 know, a mug goes flat after I draw it so it would taste
 better if you bought just one at a time."

 The cowboy replies, "Well, you see, I have two brothers.
 One is in Australia, the other is in Dublin and I'm in
 Texas.  When we all left home, we promised that we'd drink
 this way to remember the days we were together.  So I
 drink one for each of my brothers and one for myself."

 The bartender admits that this is a nice custom and leaves
 it there. The cowboy becomes a regular in the bar, and
 always drinks the same way.  He orders three mugs and
 drinks them in turn.

 One day, he comes in and orders only two mugs! All the
 regulars take 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 loss."

 The cowboy looks quite puzzled for a moment, then a light
 dawns and he laughs. "Oh, no, everybody's just fine," he
 explains.......

 "It's just that my wife and I joined the Mormon Church
 and obviously I had to quit drinking. Hasn't affected my
 brothers though."
