There was the 'Cosby Show' in America in the 1980s, which was a doctor in a beautiful Brownstone middle-class house. We just haven't created a role like that in the U.K.; it's always gangs and crime. We need to be brave.

The comedians I liked were Bill Cosby and Steven Wright, like just always as a comedic actor. I always liked Gary Larson, who's really funny for a cartoonist, obviously.

Some call-in moderators are neutral and courteous. Then there's Rush Limbaugh, who is funny and pompous and a scapegoater and hatemonger. His popularity could cause you to draw some terrible conclusions about the state of mind of the American people. It helps to remember that Bill Cosby is popular, too.

When 'The Cosby Show' came out, and everyone was up in arms about 'The Cosby Show' and that it was reflecting a world that didn't exist - but I knew black doctors. And I knew black lawyers. And I knew families that, you know, had a mother and a father and kids that were well-behaved.
