Welcome to December! This is one of the classic shorts riffed by the crew of the Satellite of Love on Mystery Science Theater 3000. It was specifically riffed as part of Experiment 609 – The Skydivers. This rendition is not riffed, though.
If The Skydivers sounds vaguely familiar, you’re remembering it as part of the Coleman Francis trilogy of films. This short came before that film. We may approach that film another day.
