Nice, pretty good armatures at work here. Very smooth.
The joke was alright.
Not very many criticisms, other than it being a little short.

Cute concept, made me chuckle.
Could benefit from more detailed animation, even just having some basic lipsync could improve this greatly.
I get the impression that you're going for a more minimalistic approach, and thats fine. But even just putting in simple movements could work wonders here.
