Two sociopaths was being locked up in a psychiatric hospital.
One day they both decide that they dont like it there and they want to escape.
They wait for nighttime and eventually they make it to the top of the building and they now stand on the edge of the rooftop, only jumpingdistance away from the next rooftop.
One of the sociopaths jump over to the other rooftop with ease, but the other one suddenly freezes and tells the first sociopath that he’s afraid that he isn’t going to make it.
The first sociopath then gets an idea. He pulls out a flashlight and shouts:
“If I shine thos flashlight over to your side you can just wall across the beam.”
But the other sociopath wasn’t going to be fooled so easily, so he shouts back at the other:
“You really think I’m that mental? You’ll just turn of the beam when I’m halfway over!”
