Good idea
The kind of moronic backwards logic is actually a pretty funny concept. The only thing is the animation. The mouth seemed to move well, but the drawings themselves just...yeah. Please work on that for next time. Also have more than one person do the voice. It could have been longer, but it works well as a short- though you might want to speed up the pace a little, otherwise people will get bored.
Yeah... good, but get better. :D
