The man's hand was hanging by a hook attached to the car door

A man and a girl go out to drive under moonlight, they stop on the side of the road.

He turns to his girl and says:

"Baby, i lov you very much but...."

"What is it honey?"

"Our car just broke down, i think the engine is broken. I'll walk and get some more fuel"

"Ok, I'll stay here and look after our stereo, there have been news reports about stereos being stolen"

"Good idea, keep the doors locked no matter what, I love you sweety"

So the guy left to get fuel for the car. after two hours the girl says "Where is my baby, he was supposed to be back by now?", then the girl hears a scratching sound and a voice saying "LET ME IN!"

The girl dosen't do it and then after a while she goes to sleep. The next morning she wakes up and finds out her boyfriend's still not there. She gets out to check and the man's hand was hanging by a hook attached to the car door
