Sure, you can redo the entry if you want to.
"The Shining" is one of the most famous horror movies of all time, and that particular scene is the most famous moment in it. The Johnny Carson show always opened with sidekick Ed McMahon saying "Heeeeeere's Johnny!" and that's what Jack Nicholson is spoofing in this scene. And in a nice counter-spoof, the Johnny Carson show once opened by showing that clip instead of having Ed McMahon do the intro. I think maybe that was on a prime-time "greatest moments" show. The movie is based on a Stephen King novel, also called "the Shining", which is a good read.
A while back I did a spoof of another famous moment from the movie, and here it is as a contest entry. The movie was playing off the fact that "murder" spelled backwards is "red rum", and I played on it some more with a red-rumped parakeet.
