A man begins to frequent a small bar in Arcata, each time ordering three martinis at once. He builds a rapport with the regulars and is seen nearly every day. After a month of visits, the bartender finally asks, "So... why do you order three drinks up front?"
"Well," replied the man, "I was always close with my two brothers, but one's moved to Ireland and the other to Australia. We decided, in the spirit of fraternity, that each time we had a drink we'd have one for each of our brothers."
The bartender found this inspiring and the tradition carried on for several years, until one day the patron came into the bar and ordered two martinis. His heart sinking, the bartender asked "Oh I'm so sorry, has something happened to one of your brothers?"
"No, no," said the man. "I've just decided to quit drinking."
