Wonderful animation as usual, and I got a laugh or two from the ending as well. It does seem a little lacking though, but not because of the length of the animation like a whole bunch of people seem to claim here.
In fact, I'm not sure where all the complaints about how short it is are coming from. It seems like a perfectly suitable length of time to me, and it doesn't need more time than what it uses in order for the gag to possibly work.
Again, wonderful work Wonchop. Can't wait to see what else you cook up. :)
