A good story

[Tyrrell]

I hate to cast doubt upon your fellow student's story but Douglas Adams wrote about a more or less identical incident that happened to him. Mr. Adams’s version took place in an English train station and the last cookie was not split but otherwise it was the same story. The story was published in a posthumous compilation of his writings called "The Salmon of Doubt" and he wrote a fictionalized version of the story in "So Long and Thanks for all the Fish".
