Go to the spot towards the end of the movie when the ghostly trio is sitting against the poll in the bar "crying" because they don't want to kill Dr.Harvey. Stinky says "Me neither, no way" and shots the gun he was carrying. If you watch in the background the bullet hits the ceiling and the pieces of it fall down on a guy (I think with blonde hair) sitting there with his head down. This "extra" is not Dr. Harvey. He has no glasses, is sitting way to far in back, and doesn't look like him.
