Comedy is very interesting because you can very quickly cross into dangerous territory. I mean look at what happened, unfortunately, (in) Paris a couple of weeks ago. They were making comics - which were really satire - but it offended people. I'm not saying the reaction was justified but there's definitely a line when you're doing comedy or satire and how it might affect somebody. That's the thing you have to watch and I think you have to be respectful of it.
