WARNING: If you are grouchy and want to stay that way, do not watch this video!

Kyle Behrend shot video of a rescued lamb named Peter Pan, shaking his little tail out of pleasure and happiness.

The video inspired Kyle to superimpose a music track over the video to make it appear as though Peter Pan and his friends, all wildly wagging their tales, were dancing along.

Peter and his friends are bound to put a smile on your face, and they are doing a good job gettng attention for Edgar's Mission, a non-profit animal sanctuary in Australia that provides homes to more than 300 rescued farm animals at any given time.
