I heard this joke before. Well, maybe I saw this and then heard it as a joke. I really like the animation. It's just one joke, but it is rather funny. It's nice to just see a cow become a helicopter. You even do more with that as the cow speeds up his speech.
Then you slow it down. You have enough for a full movie. Well, not a full movie in the strictest sense. I love how silly they look. I'm glad this mad cow thing is over by now.
