Well, I decided to put my cartoony version of the Simpsons next to my realistic version of The Simpsons for you to compare. I basically did a quick and crude Photoshop job by flipping the cartoony version horizontally, place it as the left page; then I took the original signature and carried it over and erased the "flipped" signature... and voila! I didn't feel like moving the heads around to make them match on both sides... that would be too much. After all, everyone can tell which is which, right? Right.
Enjoy the eeriness,
The Simpsons along with Monty Burns and Milhouse Van Houten were created by Matt Groening (I think, not sure how many of the characters he came up with personally)... And I believe they are owned by Fox Television...
