Ever seen a man with a beard sound exactly like a teenage girl? If not, you haven't met Matt Bittner yet.
This guy does sound design. He rabidly follows sports. He dabbles in acting...and when Matt Bittner gets into character, he really gets into character.
Watch the video closely the first time so you can tell Matt really does the girl voice. Then play it again and close your eyes. Even after you saw him do the impression the first time, it'll still blow your mind.
I see him getting some sort of a deal for a show in the very near future.
