Two and a Half Men in a Boat is a 1993 travelogue book written by English novelist, screenwriter and playwright Nigel Williams describing his travel on the Thames inspired by Jerome K. Jerome's book Three Men in a Boat.

[1] The book has been described as"a whimsical account of a lazy trip up the Thames with friends" but was written to pay a tax bill of £28,000.

[2] Like Jerome, Williams travels in a skiff with his dog Badger and two friends, BBC executive Alan (Alan Yentob[3]) and professional explorer John Paul, called JP.

At first, Alan is reluctant to go, but is persuaded to meet them halfway, after being promised the use of a mobile phone.

JP is, as an experienced adventurer, comfortable with sleeping outdoors but the rowing takes its toll.
