If I had to pick one..... tricky. David Dickinson's pronunciation of auction (i.e. 'oction') really grates, but I think for me, it's Simon Cowell. Boy George recently commented that Cowell foisted Robson and Jermoe wrecking Unchained Melody on us and we're supposed to believe he has an ear for music? And if his put downs aren't scripted then I'm going to be the next Pope!
