Not your best effort
I like your drawing style and animation, but I have to say this little animation lacks a real idea or some turning point.
Ok, some guy gets burned because of a bucket of lava, the doctor laughs at him until he dies, then he puts him into the medical waste and get hit by a madman...so what's really funny about the whole story?
Since I appreciated your previous animation and your comic I think you can do much better than that. Put one of your ideas into flash, not just your characters.
