Internet Archive Uploader note: this was a famous animation by Fred Perry of the song "You are a pirate", from the children's show "Lazytown". The song itself has been continuously popular for years but it reached a new height when in the summer of 2013, this animation was uploaded to youtube on Jul 26, 2013.
As of December 5th, 2019, this animation will apparently be removed from youtube due to the new COPPA regulations, although whether Fred Perry will do this is unknown. The current viewcount of this animation is 19,585,251 views."
