The ol' photo-video switcheroo.

You know that moment when you go to take a picture of your friends as they strike a pose for the camera, but it turns out you accidentally had it set to video, and now you have this seven-second video of everybody standing totally still with goofy, frozen looks on their faces? Well, what if it it wasn't an accident. What if it was just some mean thing you did to all the people you care about for your own sick pleasure. That'd be awesome, right?!
