'i 'm sitting in a cave in a country where everything bites you and it never rains and i 'm talking , no offence , to a herbivore that smells of a carpet in a house where there are a lot of excitable puppies , and i 've suddenly got this talent for finding jam sandwiches and inexplicable fairy cakes in unexpected places , and i 've been shown something very odd in a picture on some old cave wall , and suddenly said kangaroo tells me time and space are all wrong and wants me to be sensible ?
