For many years, 3 Irish brothers who would come to the pub every day and have a pint together. One day, 2 of the brothers left for the United States. To keep up the tradition, the remaining brother always came in at the same time, ordered 3 pints and set them on the table where his brothers would sit, then he would drink each pint, one for himself and one for each brother.

One day, he came in and ordered only 2 pints, set them on the table, and began to drink one of the pints. The bartender noticed the change in the ritual and figured something must have happened to one of the brothers in the States. The bartender came over to the brother and very solemly said, "I'm sorry about your loss. Which one of your brothers was it?"
The brother looked up at the bartender with a puzzled look saying, "what do you mean?"
"It's the 2 pints. You always get 3," the bartender replied.
"Nothin's happened to any of my brothers", he answered, "I decided to quit drinking."
