One of the best-loved classics of all ti me, Three Men in a Boat is a hilarious account of three friends and their dog on a holiday trip on the Thames in England. Harris, George, Jerome (the narrator), and Montmorency (the fox terrier) decide to take a break from their tedious routine, to restore their 'mental equilibrium'. 

And so they take a trip on the Thames between Kingston and Oxford, making certain stops at interesting places, camping out, and inadvertently landing up in comical muddles and misadventures.
