Book excerpt: The letters page of Old Git magazine continues to offer its readers an opportunity to ask and provide answers to the most pressing questions of our times. Questions such as: Would it help global warming if I left my fridge door open? What's the riskiest game of risk ever played? If I fell down a disused mineshaft would Lassie really run and get help, or just sit there licking his balls? Do Bats Have Bollocks? features a host of completely new and untrue questions and answers. With bags more rude jokes, shaggy dog stories and the odd entry from a new, bewildered editor who's wondering what the hell he's got himself into, this book is every bit as laugh-out-loud funny as last year's hugely successful volume Do Ants Have Arseholes?
