The funniest prank I can think of actually happened to me. Roughly 4 or 5 years ago when I was using a 35 mm game camera at my parents house. My parents live in the city and my friends knew that my camera was down in my parents woods. So when I was out of town my buddies went down in front of the camera and did alot of unexplicable things in front of the camera. Me not knowing this was psyched because the film was done and the counter read there was a lot of activity. So I take the film to Wal-mart and come back expecting a package full of pics. Well instead there was a little red piece of paper saying that these pics weren't able to be processed b/c of the material. I was like what the hell could deer possibly be doing that the pics couldn't be processed. Well after looking at the negatives I figured it out. Those bastards.
