Full disclosure - got this off another site. But I'm sure it will help some readers.
A cowboy, who just moved to Montana from Texas, walks
into a bar and orders three mugs of Lone Star beer.
He 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 approaches and tells the cowboy,
"You know, a mug goes flat after I draw it.
It would taste better if you bought one at a time."
The cowboy replies, "Well, you see, I have two brothers.
One is in Arizona , the other is in Colorado.
When we all left our home in Texas, we promised that we'd
drink this way to remember the days when we drank
together. So I'm drinking one beer for each of us."
The bartender admits that this is a nice custom.
The cowboy becomes a regular and always orders 3 mugs
and drinks them in turn.
One day, he comes in and only orders 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 laughs.
"Oh, no, everybody's just fine," he explains.
"It's just that my wife and I joined the Mormon Church and
I had to quit drinking."
?It hasn't affected my brothers though."
