One young teen took a while to realise he was meeting the voice of a cartoon character he had been growing up watching.
Nancy Cartwright, who has voiced Bart Simpson since the beginning of the series, gave a "really good impression" of the 10-year-old cartoon character.
However, it took a few more subtle hints before the 13-year-old she was talking to finally understood that she gave more than just an "impression".
And the look on his face was priceless!
Thanks to his lovable reaction, Nancy, who also does the voices for Nelson Muntz, Ralph Wiggum and Todd Flanders, bought ten fundraiser chocolate bars of him - and he got an encounter he'd never forget!
