As stated above, song parodies are hard. The music and singing might be the hardest part.
I wonder if a different type of parody could be easier and more enjoyable. For example, the Holy Grail parody in the FIRST Stronghold kickoff video. Nobody needs to sing or play instruments. And goofy costumes are part of the FIRST culture already.
So, what about a "FIRST favorite movie scene parody" competition??
