Midnight Matinee's production of The Day The Clown Cried
Some fairly twisted individuals riff on Jerry Lewis by way of his pet project The Day The Clown Cried by performing it as a radio play of sorts. A little niche, but damn funny if you're hip to what a goofy concept that film was. If this is new to you, this is required reading first.
