Sean (reading in a higher-pitch-than-normal voice): Book bum, btardust! Bat's bandruff, beer. Brian (sitting beside Sean reading something else): Read properly. Sean: Bello --- Bearth. Brian: READ PROPERLY!! Sean: I am speaking tortoise language. Me (puzzled): What are you reading Sean? Sean turns to the book cover (photo above): Bpace Btars band Blimy Bayliens.
(Sean's reading this as I type and just gave a big giggly grin. By the way, the first line he read was, in human language, "Look Mum, stardust!" "That's dandruff, dear." and the second "Hello --- Earth.")
