15. Jedward – For some unfathomable reason, millions of people became infatuated with these irksome Irish twins when they appeared on The X Factor in 2009. Proof, if ever it was needed, that the general public are idiots. Despite the fact they can't sing and bound around stage like a hyperactive 11-year-old after too many e-numbers. John and Edward Grimes count the likes of Prime Minister David Cameron (urgh), Britney Spears (urgh), Westlife (urgh) and Peaches Geldof (LORD, GIVE US STRENGTH) amongst their admirers. Says it all really.
