On Thursday, a guy's unbelievable "girl voice" went viral, and now he's back with another video. Matt Bittner, an actor, musician, and sound designer who — despite his beard and naturally deep voice — can flawlessly imitate a woman's voice. In his latest video, he explains that he "explicitly asked [his friend] not to put it on the Internet," but since he's gone viral, he'll give fans another impression. Watch Matt's latest video above, then check out the original below. And if you can't get enough, watch even more must-see viral videos. This one is definitely real, but for 29 fake celebrity impressions, you'll want to see Rob Cantor's ridiculous video.
