"The Little Man on the Subway" is a fantasy short story by Isaac Asimov and Frederik Pohl, originally published in the 1950 issue of Fantasy Book, and included in the 1972 collection The Early Asimov. It was initially written in 1941 by Asimov's friend, the author/agent/writer Frederik Pohl, under the pen name of James MacCreigh. Unable to get it right, Pohl asked Asimov to rewrite it, which he did. It was rejected by John W. Campbell and Asimov forgot about it. The story was finally sold to Fantasy Book in 1950.
