The folks at nerdbastards.com have posted up a video of this gentleman from Japan who has an amazing talent:

Hikakin is a young Japanese male, whose occupation is listed as Human Beat Boxer and I have to say, he may be one of the best I have heard. Using both, his mouth and nose, he has performed a melody of Ken Vs. Dhalsim from Street Fighter II that is just amazing.

Yes, he is ridiculously good. Can you do that?
