I carry up to 2.5 tonnes of an oil-like balm in my huge, coffin-shaped head. I have a brain the size of a basketball, and on that basis alone am entitled to my opinions. I am a sperm whale. When I breathe in, the fluid in my head cools to a dense wax and I nosedive into the depths. My song, available on audiocassette and compact disc is a comfort to divorcees, astrologists and those who have “pitched the quavering canvas tent of their thoughts on the rim of the dark crater.” The oil in my head is of huge commercial value and has been used by NASA, for even in the galactic emptiness of deep space it does not freeze. I am attracted to the policies of the Green Party on paper but once inside the voting booth my hand is guided by an unseen force. Sometimes I vomit large chunks of ambergris. My brother, Jeff, owns a camping and outdoor clothing shop in the Lake District and is a recreational user of cannabis. Customers who bought books about me also bought Do Whales Have Belly Buttons? by Melvin Berger and street maps of Cardiff.
