The first time I ever saw a movie wait until after the end credits to show one final scene and thereby blow your mind to the possibilities of what could happen next was at The Young Sherlock Holmes (nullus). I loved it though, and can actually remember sitting through the end credits of a bunch of movies when I was growing up hoping they would put a teaser at the end of the credits. Now we have the internet to tell us what to do. And I control the internet.
