I was watching the old MGM short "Red Hot Riding Hood" on the Turner network that shows cartoons 24 hours a day*, and they ran this interesting factoid: the Hays Board rejected the original ending where the lustful wolf is forced into a shotgun marriage to the grandma of Red. The acceptable replacement ending? The wolf shoots himself in the head.
Illuminating, don't you think?
*No, this network would not be the Cartoon Network. Cartoon Network doesn't show cartoons 24 hours a day. (Despite making an claim earlier to do so until the "end of time".)
