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."

Figure 1 From U.S. Patent No. 4,608,967
