Just when we thought U.S. patents couldn't get any sillier, we found a patented invention for an "Apparatus For Simulating a 'High Five'"!
Issued to Albert Cohen of Troy, New York on 18 October 1994, U.S. Patent 5,356,330 solves the following problems:
...the hand-arm configuration of the invention 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. Further, the hand-arm configuration synergistically improves the hand-eye coordination of a user and/or, depending upon specific placement, provides an exercise device for enhancing the jumping skills of a user. More specifically, when the hand-arm configuration is mounted at a sufficient height above the normal reach of a user, the user must jump upwards to strike the simulated hand, thereby simulating many of the jumping drills commonly practiced by basketball players. As such, the leg strength and coordination of a user may be improved through the practice of the present invention.
No, we're not making this up! Here's what the invention looks like:
Here's hoping you have a positive event to simulate with a convenient outlet for your excitement this weekend!
