What do you know? "Toothing", the alleged British cultural phenomenon where commuters pair up for casual sex using their mobile phones,
turned out to be a hoax; or, at least, started off as one; who knows, perhaps someone somewhere did actually get lucky (either that or some disease) by sending address-book entries from their phone on the Tube, as implausible as it may sound. The hoax did take in quite a few news organisations, including the BBC and WIRED.
