After a favorite sports team scores a winning point, it’s understandable to want to give out high-fives to your fellow fans. But, what if no one is there to receive your high five? Enter the “high five apparatus” for which U.S. patent number 5356330 was granted to inventor, Albert Cohen. It specifically “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 1994 patent description. Simply affix the high-five machine to a wall or set it on a table, and improve hand-eye coordination and mood by giving the plastic hand and stuffed arm (with sleeve color to match your team’s colors) high-fives at your convenience. No friends necessary!
