These are both videos based on a parody of 'Born This Way' by Lady Gaga. Personally, I don't like her music, but that's because I don't listen enough to the radio to know any of her songs. However, I did find both of these videos very amusing in their own ways. They were uploaded to YouTube only 1 day apart and of course, they are having their own little debate over whose idea came first. Who cares! Just enjoy the videos.
And by the way, I really am doing more than just spending my summer finding random YouTube videos about Calculus. =D
