Silly Patents: Apparatus for Simulating a "High Five"

US Patent #5,356,330 covers an apparatus that can be used to simulate a "high five". In simpler language, it is a fake arm with a readjusting elbow joint that allows high fivers to practice their high five-ing technique independently of a friend or acquaintance. A diagram of the patent is included below:

I found this patent particularly interesting due to its cited background. I have provided its full text for the purposes of added humor below: 
"During a televised sporting event, a "high five" is commonly shared between fans to express the joy and excitement of a touchdown, home run, game-winning basket, birdie or other positive occurrence. Unfortunately, as known in the art, a "high five" requires the mutual hand slapping of two participants, wherein a first participant slaps an upraised hand against the elevated hand of a second participant. As such, a solitary fan is unable to perform a "high five" to express excitement during a televised sporting event."

Another interesting feature of this patent is its prior art citations, which come from a variety of different sources. From a self-erecting football dummy to a "doll giving particular vocal responses on movement of particular appendages", each citation seemed to come from a different industry, but I could see how they all had an effect on the patent's novelty.
