Getting a cast for a broken bone is no fun -- unless you happen to be as lucky as this little girl and there's a medical professional on hand who's also a pretty awesome rapper.
Watch the video above in which this Staff Sergeant and Army medic raps a totally comprehensive lesson on how to take care of a cast. It's catchy, easy-to-follow and definitely educational.
After listening, we've learned some important foot cast maintenance rules.
If the cast feels too tight, "don't hate, just elevate." And never ever get your cast wet -- but if you do, just blow dry it on a low setting.
We're left wondering if this doctor has raps for any other injuries. If so, we'd be first in line to hear every single one of them!
