"Bon-Bon" is a comedic short story by Edgar Allan Poe, first published in December 1832 in the Philadelphia Saturday Courier. Originally called "The Bargain Lost", it follows Pierre Bon-Bon, who believes himself a profound philosopher, and his encounter with the Devil. The story's humor is based on the verbal interchange between the two, which satirizes classical philosophers such as Plato and Aristotle. The Devil reveals that he has eaten the souls of many of these philosophers.
The story, which received moderate praise, was originally submitted by Poe as "The Bargain Lost", and was his entry to a writing contest. Though none of the five stories he submitted won the prize, the Courier printed them all, possibly without paying Poe for them. This early version of the story has many differences from later versions, which Poe first published as "Bon-Bon" in 1835.
