'The Lottery Ticket' by Anton Chekhov

And here comes the winning ticket! The numbers are... When Ivan Dmitritch reads the newspapes, he sees that the winning numbers from the lottery are very much the same as his wife’s ticket. They immediately start to daydream about all the things they can buy now and the life they are going to have from now on. And it is exactly because of this that they fail to notice the obvious problem. Enjoyable and amusing, "The Lottery Ticket" is one of those stories of Chekhov that can be grouped under the general "stories with a twist". A recommended read, by all means.
