Look look look I have taken a photograph of a ghost. Looksie:
See the man in the top right? He only has 3/4 of a head! He is a ghost!
Pause for sanity. I’m guessing that he’s a painting on the back wall, or something, but I don’t remember seeing one at the time. Relative sizes suggest he would be something of a ginorminous fellow, were he to be real. End pause.
ARRGH A GHOST.
