Short stories

Short stories are good when you don’t have much time but want to read something (why welcome, Captain Obvious).

Here are few that I really liked:
Isaac Asimov: The Last Question
Terry Bisson: They’re Made out of Meat
Ambrose Bierce: Moxon’s Master
Edgar Allan Poe: The Pit and the Pendulum

I strongly advise you to read at least the first two.

Somehow, I wasn’t that impressed by other short stories such as Nightfall (it wasn’t that bad, but somehow I expected the generally accepted best short story to be better, it was also longer than needed—the shorter the better) or An Occurence at Owl Creek Bridge.

And finally, I would like to ask for your advice. Do you know any really good (and possibly short) short stories?
