Sonic the Hedgehog made a cameo on The Simpsons!
You can see a sort of reflection of a Sonic-like guy to the right of the photo. Although he does look "Simpsons-Styled". Mario and Luigi are funny looking here too...The characters are trying to get Bart to steal a video game. Episode #139 (Season 7) "Marge Be Not Proud".
