Three Men in a Boat (To Say Nothing of the Dog) published in 1889 is a humorous account by English writer Jerome K. Jerome of a boating holiday on the Thames between Kingston and Oxford. The book was initially intended to be a serious travel guide with accounts of local history along the route but the humorous elements took over to the point where the serious and somewhat sentimental passages seem a distraction to the comic novel.

One of the most praised things about Three Men in a Boat is how undated it appears to modern readers the jokes seem fresh and witty even today.
