My friend Andrea brought this to my attention tonight. It's an absolutely hysterical "mashup" of Monty Python's song "Knights of the Round Table" from "Monty Python and the Holy Grail" with selected cuts from the original "Star Trek" series. Whoever put it together did an absolutely superb job matching the Star Trek scenes with the Holy Grail scene where the song plays over.
It's just 1:39 long, but it's simply terrific. I hope you enjoy it. I sure did!
