There's a common complaint with a lot of nerd rappers, and it's one I for the most part agree with: that weak production and sloppy rhymes often get a pass because of the subject matter.

Not here.

This is freestyle rapper Surgeon General showing that he can go through the Mortal Kombat roster on the run, throw in some guns, blood, take a sharp left into Street Fighter avenue and just keep on going.

A warning if you're at work or there are kids around: this is very NSFW.
