It involved this magic hat.
In 2007, while actor Daniel Radcliffe of Harry Potter fame was in London appearing in the stage play "Equus", he came up with a sly trick to frustrate the hoards of paparazzi waiting to take his photo after the show. He explained his plan to Jay Leno on "The Tonight Show":
"I would wear the same outfit every single time with different T-shirts underneath but I would wear the same jacket and zip it up so they couldn't see what I was wearing underneath, and the same hat. So they could take photos for six months but it would look like the same day. They became un-publishable, which was hilarious because there's nothing better than seeing the paparazzi get really frustrated."Daniel Radcliffe Is Growing Up, CBS News>>
