My all-time favourite is "Does my bum look big in this." I laughed till I cried at some of it; it has a certain appeal to women of a certain age, LOL. Runner-up has to be "The Haunting." (Or was it "the Haunted?") Anyway it was set round a bothy in Scotland; great book, but a bit scary........
Not sure if I should admit this, but I have kept my favourite book from when I was a child, "Shadow the sheepdog.")
