"Big Game" is a short story (1,000 words) by the American science fiction writer Isaac Asimov.
He wrote it in November 1941 when he was 21, failed to sell it to any magazine, and eventually lost the manuscript.
However a fan of his, Matthew B. Tepper,[1] discovered the missing manuscript in a collection of Asimov's old papers which were archived in the library of Boston University and sent it to him.
Asimov included it in an anthology he was editing at the time, Before the Golden Age (1974), although he pointed out that he had re-used the plot of the rejected story to write "Day of the Hunters" in 1950.
A drunk man tries to convince his audience that ten years ago he built a time machine and travelled back to before the extinction of the dinosaurs, where he met an intelligent race of humanoid dinosaurs who communicated with him telepathically.
