An Irishman walks into a bar in Dublin, orders three pints of Guinnessand sits in the back of the room, drinking a sip out of each one inturn.When he finished all three, he comes back to the bar and orders threemore.The bartender says to him, "You know, a pint goes flat after I draw it;it would taste better if you bought one at a time." The Irishmanreplies,"Well, you see, I have two brothers. One is in America, the other inAustralia, and I'm here in Dublin. When we all left home, we promisedthat we'd drink this way to remember the days we all drank together."The bartender admits that this is a nice custom, and leaves it there.The Irishman becomes a regular in the bar and always drinks the sameway: heorders three pints and drinks the three pints by taking drinks from eachof them in turn.One day, he comes in and orders two pints. All the other regulars in thebar notice and fall silent. When he comes back to the bar for the secondround, the bartender says, "I don't want to intrude on your grief, but Iwanted to offer my condolences on your great loss."The Irishman looks confused for a moment, then a lights dawns in his eyeand he laughs. "Oh, no," he says, "Everyone is fine. It's me...""...I've quit drinking!"
