A man walks into a bar and orders three drinks. The bartender serves him the drinks, and the man takes a sip of one, then the other, then the third until all contents of the three glasses are drained. He does this for some days before the bartender asks him about this habit. The man replies, "I had two older brothers, my best friends in the world. Every week we used to buy a round of drinks and talk about what was going on in our lives. Then one brother moved to England and the other Australia, but before they did we still promised to drink like this to remember the old times." The next day the man orders only two drinks and sips them in the usual way. Fearing something might've happened to the other brothers, the bartender asks, "Aren't there three of you." the man smiles and says, "There are. But I've just quit drinking."
