How Inventive! (No. 9)
Who hasn't needed a pat on the back at some point? In case you don't have a friend handy, Ralph Piro invented a device that helps you pat yourself on the back. U.S. Patent 4,608,967 describes a "self-congratulatory apparatus having a simulated human hand carried on a pivoting arm suspended form shoulder supported member. The hand is manually swingable into and out of contact with the user's back to give an amusing or an important pat-on-the-back."
