This is just plain scary. Kent, a guest at an unnamed hotel, awoke to discover a rolled-out piece of paper on the carpet underneath his peephole. On closer inspection, he realised it'd fallen out of the peephole.
When he left his room, he found he was able to remove the outer glass on the peephole, blow on the rolled-up paper sitting in the hole so it fell out (onto the carpet of his room, where he found it that morning), and peer straight into his room.
He told the hotel, of course, who were "mortified, and instantly sent housekeeping door-to-door", but nonetheless it's worth always checking peepholes if you're worried about someone spying on your sexytimes. Or clipping of toenails in bed. [Flickr via Boing Boing]
