We discover you don't want a windy day in the Farmer's backyard. That's especially true if things like kites or balloons are flying about. The sheep are mesmerized by them and all kinds of crazy things can happen.
The writers of this episode really used their imaginations to make another very funny episode out of almost no story. (The story is described above: a windy day, a kite with a face on it hovers by, and the sheep, although terrified at first, then do everything they can to get it out of a tree when it gets stuck there. That's it....but a lot of good sight gags evolve from this.)
This starts of slowly but quickly builds momentum and is another "must" for your Shuan the Sheep collection.
