When I was in school, and manifestly unpopular, I still enjoyed going around and taking pictures. My Polaroid One Step had a slow lense and a large image area to expose, onto slow film. It took a lot of light to make a good picture, so I had a powerful flash. Some people would object to me popping in to take random pictures, so I started telling people "It's okay, I'm with the yearbook committee." I got away with this for a while.
Until I happened across a room of pretty girls, and took their picture. The old "yearbook committee" trick of course failed, as this was the yearbook committee. Oops.
