Okay, this is hysterical. Safe for all viewers, and soooo funny…It’s an AMV (anime music video) made by some wonderful talented person who fitted Gravitation images to a Shakira song. I think it would be funny whether you knew the show or not, but just in case:Shuichi, the pink-haired boy, is in love with Eiri, the tall cool blonde. Shu will do anything to win him.  Shu is also a rock musician, at the beginning of a promising career. Hiro, the redhead, is his guitarist and best friend. K, the blonde with the gun, is their manager. He will do anything to make them stars.
I hope the video inspires you to watch the show, because it’s even better…
