Britains got talent, the three singing lads, in their interview at the beginning, the short guys hair moved, he's sat on the car and watch carefully and the whole head of hair just swivelled on his head! How strange! If you are able to rewind your tv, have a look, it's just after the bit where the tall guy does the impression of his mother.
Watch it on here - I haven't had time to watch it again and find the interview but I seem to remember it was about three quarters of the way through the programme.
