I guess I'm just going out and saying I didn't care much for this. It seemed to be just a single gag. I do like the idea of a talking can, though. I think it's cute how you called him "canny". It reminds me of that great "South Park" episode. His voice is pretty funny too.
It is, in fact, fine for what it sets out to do. It seems like one edge of the can didn't have those sharp blades. I still praise this for being mostly well animated. While not too good, some people do like it. Not really for me.
