A man walked into a haunted house wanting to get a picture of a ghost with his instamatic camera. After a couple hours, he finally saw one. It was a friendly ghost who actually posed for the picture.
The man took the first picture, but it turned out too dark. So
the ghost posed for another one, and the picture again turned out dark.
The ghost had to go so the man did not get a picture.
Goes to show that the spirit was willing but the flash was weak.
