This St. Louis man has built himself his own secret "man cave" behind a fake bookshelf under the stairs in his home.<br /><br />Filmed on January 18, the footage shows how he is able to pull a book partly from the bookshelf allowing the shelf to swing open like a door unveiling the unsuspecting cubby hole.<br /><br />The filmer explained online that he built the secret compartment because of his child recently learning how to use doorknobs.
