The curse of being a well-loved celebrity who reaches old age is that you're going to wake up to find that everyone thinks you're dead at least once every month - just ask Sir Patrick Stewart. Such is the case with beloved American comedian Bill Cosby, who has dared to reach the age of 75 without dying, which has not stopped people whetting their appetite for obituaries, as a Facebook group called "R.I.P. Bill Cosby" was set up in August 2012. Cosby's way of proving that he's still alive and kicking was not to address the issue directly, but to Tweet an image of himself from The Cosby Show, wearing one of his classic bold sweaters. His previous responses have included telling people "I'm still alive, now cut it out", but now it seems Cosby just wants to confuse people by making us think it's the 80s all over again.
