Street Fighter II Soundtrack And Sound Effects Performed Acapella

This is a video of the Maytree Acapella Quintet (previously) performing the soundtrack and sound effects of Street Fighter II ENTIRELY WITH THEIR MOUTHS. Me? I only use my mouth for eating and yelling at people. They do an amazing job, and the faces they make were definitely value-add as far as I’m concerned. And I am concerned. Mostly about this thing on my thigh — will you take a look? “It was a no yesterday, and it’s still a no today.” What about after a few drinks? “Then it’s a maybe.” Bartender — two of your slipperiest nipples and keep ’em coming — I need my friend here to play doctor!
