Joke time:
An Irishman walks into a pub one day and orders three pints. He sits down with them and slowly drinks them, one after the other, and then leaves.
The next day he comes back, and again he orders three beers, drinks them, and leaves. And the next day, and the day after that.
One day, after he orders his beers, the bartender asks him why he doesn't just get them one at a time so that each one is fresh when he drinks it. The Irishman says, "Well, it's sort of a family tradition. I have two brothers, and we used to drink together all the time when we were younger, but then they both moved away and we don't see each other so much anymore. So now, when we drink, we each order three beers, one for each of us, and it's like old times again." The bartender and the pub's other regulars think that this is pretty touching.
Then one day he orders two beers instead of three, and the whole pub goes quiet. The bartender approaches him and says that he's very sorry for his loss.
And then the Irishman says, "Oh, it's nothing like that! My doctor just told me I have to give up drinking."
