Ghost Hunters - Eastern State Penitentiary Investigation
This is a clip from the first investigation of Eastern State. About six minutes into the clip, the guys are reviewing the evidence and discover an interesting piece of footage. It's unsure if it is an actual ghost or someone's attempt at a joke. I sort of think it is a fake. Someone who knows that place well could easily pull something like that off, but I could be wrong.
You decide for yourself.
