Rolf Harris

From Frikipedia

The non-thinking man's Tony Hart.

Rolf has a litany of talents, including playing the didgeridoo and wobble board, and making random drawings and paintings of stuff.

Rolf used to present a cartoon show on 80's TV, where he would draw a Warner Brothers character on a big piece of paper and then show a cartoon of that character. This led many kids to believe in the Holness that Rolf drew all the Warner Brothers cartoons. He didn't, he just enjoyed flirting with copyright regulations.

Rolf would occasionally draw huge pictures and taunt the viewers by asking them if they could tell what it was yet, after he'd just drawn a small green line and some squiggly bits.

Rolf also advertised milk at some point. Though he was bubbish at it.
