Um
You're the cutest girl I've ever seen in my life,
But it's over now, and with my knife!
Di-Diane, Di-Diane, Di-Diane, Diiiii-ane!
Di-Diane, Di-Diane, Di-Diane, Diiiii-ane!

Er, yeah. Anyway, it was okay... but seemed to lack, um, direction. Why did that guy suddenly turn from a pedophile into some kind of drug dealer? Why was that weed acting like acid, and that acoustic guitar like an electric? The humour was also... not all that funny. Like, the buns joke. It was stupid in the first place, and the timing and delivery wasn't good either.
Also, you really need to fix the volumes for sounds. I found myself needing to change the volume from really high to really low, several times, and at a couple of points needing both simultaneously for different things.
So, yeah, animation was good, humour could have been better, story could have been... clearer, sound needed tweaking.
