This "... walks into a bar" joke is kind of universal. Just add in the fictional name of your choice...
_______ walks into a bar in London, orders 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."
_______ replies, "Well, you see, I have two brothers. One is in Dubai , the other in Canada and I'm here in London. When we left our home country, we promised that we'll drink this way to remember the days when we drank together."
The bartender admits this is a nice custom and leaves it there.
_______ becomes a regular in the bar and would always drink the same way. He'd order 3 beers and drink them in turn.
One day, he comes in and orders only 2 beers. All the other regulars notice it and they fall silent.
When he comes back to the bar for the second round, the bar tender says, "I don't want to intrude on your grief, but I would like to offer my sincere condolences on your great loss."
_______ looks confused for a moment, and then he laughs.... "Oh, no," he says, "Everyone's fine; both my brothers are alive. The only thing is . . .
I have quit drinking"!!!
