Going in the right direction...
First of all, increase your frame rate. Try using 25 frames per second or upwards... this will get rid of that choppiness ;)
Obviously not a terribly original storyline -- just CT with quirky humor added in. However, there have been things done like this and done quite well, so it's possible. Your animation skills are headed in the right direction, you just need to polish up on a few things first.
Good luck ;)
