Another addition to unbelievable british children's tv shows

This showed in the 80s - yes it's true, and it is a children's cartoon. Make sure you watch all of it, the lines just get better and better...

Rainbow

Actually just found out that this is an adult version, made for a internal staff Christmas edition. However as it is now widely circulated on the internet, and shown in adult TV shows many people who saw the original Rainbow as kids have this episode firmly associated with the series in their mind.
