HURRAH. Relief is at hand to silence loudmouth mobile phone users. A gadget the size of a cigarette packet has been invented which can cut off noisy nuisances at the flick of a switch. They've only just started surfacing in Britain, where they have yet to be legalised, but cost £130 abroad. Worth every penny! The zapper works in a 30-metre radius, transmitting signals which stop the phones working. Oh what fun. Get me an order in quick, or better still, can someone invent a machine that makes them explode?
