What is the point of Rolf Harris?

He's been over here ever since I was a kid (a very long time ago) - why is he still boring the pants of everyone on our tv screens? All I've ever seen him do is sing that stupid song 'two little boys', blow into his bloody didgeridoo, or talk to the cats and dogs on animal hospital. Oh yeh and flex that silly sheet of metal. Why doesn't he go back to Australia the silly ****.
