The pacing seemed a bit off but that pun at the end. Nice. Only thing I would really suggest is editing your dialogue in audacity or something to remove that grainy background noise. Some soft music maybe? Idk, good job on the animating! I like that ren and stimpy vibe with the facial expressions.

I think the voice acting really made it. Plus the little things, his head blows up and the other guy is just smiling like a dumbass. It was like a two second scene but that really got me. Nintendo!
