Do you like calculus? Do you like the Bohemian Rhapsody? Check out the Calculus Rhapsody. Everyone I've shown it to immediately breaks out into laughter (assuming that they have had calculus).
This video was made by a previous co-worker's son for a high school calculus project. The lyrics, music, vocals, and video were all produced by high school students for the project. Not too bad for kids just learning how to derive.
