In addition to that sweet, sweet cash, voice-over actors enjoy the added benefit of not being mobbed in public by starry-eyed psychopaths. Nancy Cartwright, for example, is one of the most successful actresses in all of television—having served as the voice of Bart Simpson since the dawn of time—yet most people have no clue what she looks like.

In the below video, shared via Cartwright’s Spotted Cow Entertainment, the actress surprises a kid selling chocolate bars for his school by not just buying a bunch of the stuff but also by revealing she’s the voice behind one of the most iconic characters of all time.

It’s funny, at first, the way the kid is like, “Why is this weird-ass lady doing Bart Simpson impersonations at me?” He smiles politely, the way you do when strangers try to involve you in bits, but he’s soon floored by the revelation that this is no mere enthusiast.

Perhaps even more heartwarming than his reaction to Cartwright’s reveal is the kid’s courteousness, which you wouldn’t necessarily expect from a 13-year-old boy who looks like a teenage Kurt Cobain.
