"Old-fashioned" is a science fiction short story by American writer Isaac Asimov.

The story was written at the request of Kim Armstrong, editor of Bell Telephone Magazine, with the stipulation that it be 3,000 words and center on a problem in communications.

Two astro-miners in the asteroid belt, Estes and Funarelli, are badly injured when their spaceship is damaged by the tidal effects of an uncharted black hole.

In desperation, Estes hits on the idea of going outside the ship and throwing small rocks at the black hole.

The attempt works and within days, an unmanned drone ship with supplies arrives from Earth.
