Airports are prime targets for paparazzi. Celebrities, unless they're going straight to their private jet, are subjected to the long lines and uncomfortable seating with the rest of the public. It's the perfect opportunity for a quick "Stars! They're Just Like Us!" Snap shot.
Understandably, some celebs don't appreciate being photographed in their pre-flight sweats. Goth singer and musician, Marilyn Manson, figured out a way to avoid these paparazzi ambushes. He wrote the word "F*#k" across his face so that photographers couldn't sell photos of it.
Apparently Manson was apologetic about the profanity to his fellow flyers though. He tried to cover it when he was around children and explained his plan to their parents. It worked too - no paparazzo could sell a photo of Manson with his temporary face tattoo.
