well youtube had to get there, by monitoring what you watch most just like amazon monitors what you buy the most of they then make recommendations and these were youtube recommendations to me this morning.
great animations, and the punchline at the end is built up differently in each one,
How many scenes? How many shots in each scene, from who's perspective, camera angle and which type of lense was used to show and tell you the story to keep the tension and momentum going?
As animators, the big mistake a lot of people make is to think they have a traditional stage and that everything happens in one place and from one point of view. with CG you can have a fly's, wom's or eagle's view of the action.
A lot of the time it'll be a combination of all three and without it the gag doesn't work, so only when you notice each shot, you can see how simple or complicated the storyboarding was for each scene but you'll have noticed how much planning has gone into it.
have fun
