Have you ever seen the person who does the voice of Bart Simpson on long running cartoon series The Simpsons?
It's actually a woman named Nancy Cartwright. Many people don't know that, including 13 year old James. See, James met Nancy while selling chocolate bars for his school's fundraiser. Little did he know he was talking to the person behind Bart Simpson!
She starts by impressing him with her Bart Simpson "impression" and then later shocks him when he finds out she IS the voice of Bart.
SO COOL. Check out the video below.
