So there are a bazillion shows on TV about ghost hunters. They go into these creepy locations in the dark and try to determine if they are haunted or not. It's too bad the shows are such farce. Why don't they ever have cameras on their heads? They always have audio recorders running, but never video. Gee, I wonder why. I mean, half the claims they make are "Did you see that?" "I saw something at the end of the hall!" "Oh my God, check this out!"

No, we didn't see anything because the camera wasn't there.

Any actor can feign a shiver or pretend they saw something. But if you're trying to demonstrate paranormal activity, the proof is in the pudding, isn't it? :)
