There is nothing worse than annotated humour.

That's what fiction writers do: create characters and do terrible things to them for the entertainment of others. If they feel guilty enough, they write happy endings.

When you're young, with less on the line, it's easier to be audacious, to experiment. So I introduced the concerns of my generation - politics, sex, drugs, rock-and-roll, etc. - to the comics page, which for many years caused a rolling furor.

Comic-strip artists generally have very modest ambitions. Day to day, we labor to fit together all these little moving parts - a character or two, a few lines of dialogue, framing, pacing, payoff - but we certainly don't think of them adding up over time to some larger portrait of our times.

When you're young, you don't feel iconoclastic - you're just kind of doing what seems natural, what moves you.

That's for the readers to adjudge, but I will say that in general public commentators have nowhere near the clout that we enjoyed 35 years ago, the age of four TV channels and no Internet, ... As far as I'm concerned, it's all good. You can't have too many voices in a democracy. Talented people will find their audiences.
