High-Five Machine (US 5356330)

After a favorite sports team scores a winning point, it's understandable to want to give out high-fives. But, what if no one is there to receive them? Enter the high-five machine, which "allows a user to simulate a 'high-five' in celebration of a positive event, thereby providing the user with a convenient outlet for the release of excitement," according to the 1993 patent. Simply affix the high-five machine to a wall or set it on the table, and improve hand-eye coordination and mood by giving the plastic arm high-fives at your convenience. No friends necessary!
