Imagine if you will a boy standing on a couch with his sister holding a toy snake. Now imaging that his father comes over with a camera and tells the boy to "do something." So the boy starts to swing the snake.

First he swings it left...

Then he swings it right...

Then he swings it left...

Then he swings it up...

Then he swings it left...all the time hamming it up for the camera

with Daddy yelling encouragement until...

uh-oh! Maybe I shouldn't have been so encouraging...
