OMG, that was great! It combined two of my favorites, AstroBoy and Weird Al Yankovic!
I hope your youtube video doesn't get yanked due to their new restrictive copyright police, but Weird Al Yankovic would approve of your parody! (Really, if it gets yanked, try to contact him and ask for his permission to use the music. He would grant it!)
BTW your ability to select scenes and sync them to the music is uncanny. Like the "egg salad sandwich" and "disbelief" (the look on Tawashi's face!).
Seems someone else had made a Youtube parody of this song with "Danny Phantom"
