Write the theme of three men …

Three Men in a Boat , published in 1889, is a humorous account by Jerome K. Jerome of a boating holiday on the Thames between Kingston and Oxford. 

The story begins by introducing George, Harris, Jerome and Montmorency, the dog. The men are spending an evening in J.'s room, smoking and discussing illnesses they fancy they suffer from. They conclude they are all suffering from 'overwork' and need a holiday. A stay in the country and a sea trip are both considered, then rejected (J. describes the bad experiences had by his brother-in-law and a friend on sea trips). Eventually, the three decide on a boating holiday, up the River Thames, from Kingston upon Thames to Oxford, during which they'll camp, notwithstanding Jerome's anecdotes regarding previous mishaps with tents and camping stoves. 

They embark the following Saturday. George must go to work that morning ("George goes to sleep at a bank from ten to four each day, except Saturdays, when they wake him up and put him outside at two") so J. and Harris make their way to Kingston by train. They are unable to find the correct train at Waterloo Station (the station's confusing layout was a well-known theme of Victorian comedy) so they bribe a train driver to take his train to Kingston, where they collect their hired boat and start their journey. They meet George later, up-river at Weybridge.
