Improvisation - Part of Being a Good Composer?

Series three of hypothetical is on Dave at the moment. If you've not seen it before, Josh and James present it. Comedians are thrown into hypothetical scenarios and see how well they deal with them. So it's all improvised. And I think the thing is with this show, as opposed to maybe some other panel shows, is you're all kind of more supportive of each other at feels,. rather than everyone trying to get the last line or the best joke in. All of that's taken out.
