Old Man Jefferson

It was a mild and foggy night, and it was Jeff's birthday. It was about 12 o'clock, and the six boys who were staying at Jeff's house were telling ghost stories. Joel was saying how he heard some guys talking about old man Jefferson's death, and how if you stay at his grave at night, he'll reach through the ground and grab you. Then he heard them say it will scare you so much you will die.
Chris raised his eyebrow in doubt and said, "I don't believe that!"
"Well, why don't you stay there for one whole night," Kevin replied.
"Fine then," Chris answered back boldly.
So off Chris went with a pillow and a blanket. The boys layed in their beds and waited for Chris to come back.
When they woke up they expected to see Chris in his bed sleeping but there was no sign of Chris. They walked over to the cemetery and saw Chris on the ground. He was dead. They saw that his shirt was caught on one of the stakes that was attached to the gravestone, probably so it wouldn't be stolen.
There was an autopsy done and they found the cause of death, FRIGHT!
