Reminds me of this classic:
[FONT=times new roman,helvetica]An enterprising journalist decided to get the scoop of the day by photographing a rumored fearsome phantom in a haunted house. Armed with only his camera, he entered the house. A ghost descended upon him, clanking chains et al. He told the ghost "I mean no harm - I just want your photograph". The ghost was quite happy at this chance to make the headlines - he posed for a number of ghastly shots.
The happy journalist rushed back to his dark room, and began developing the photos. Unfortunately, they turned out to be black and underexposed.
His editor asked, "So what happened?"
The journalist hung his head and said: "The spirit was willing but the flash was weak."[/FONT]
