I've seen these on a few other blogs and decided to go check it out and see if I could make a character of myself. If you go to the Simpson's movie site, there is a link there called Create Your Simpsons Avatar. Its sooo much fun to do!
The scary thing is that this actually looks a lot like me. The hair color, glasses, face (you can even pick you own nose), and the clothes are all me. I was even thrilled to see that they had a skull for the t-shirt. :)
Go make your own character, its very cool!
