This particular joke won an award for the best joke competition Organized in Britain:

A man walks into a bar in Londonand ordered 3-glasses of beer and sits in the backyard of the room, drinking a sip out of each one in turn.

When he finishes, he comes back to the bar counter and orders 3 more. The bartender asks him, “You know, beer goes flat after I fill it in the glass; it would taste better if you buy one at a time.” The man replies, “Well, you see, I have two brothers. One is in Dubai, the other in Canada and I’m here in London. When they left home, we promised that we’ll drink this way to remember the days when we drank together.”

The bartender admits that this is a nice custom and leaves it there. The man became a regular in the bar, and always drinks the same way. He order 3-Beers and drinks them in turn. One day, he came in and ordered only 2-Beers All the other regulars 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 sincere condolences on your great loss.”

The man looked confused for a moment, then he laughs.... “Oh, no,” he, said, “Everyone’s fine - both my brothers are alive”. The only thing is I just quit drinking...!!!
