I consider myself a pretty knowledgeable Sonic the Hedgehog fan (at least of everything before the horrible 2006 game), but I have to shamefully admit to not knowing a single one of the interesting facts in Did You Know Gaming's newest video.

For instance, apparently Sega originally designed Dr. Robotnik (I refuse to call him Dr. Eggman) as a hero for another game. Also, Sonic originally had a human love interest called Madonna. That idea was thankfully scrapped by Sega of America for being too "Japanese."

You can learn more bizarre Sonic trivia by watching the video after the break.
