They have become part of us in that if we get dressed up as them, we don't actually have to have a script. You can just become them. You just become nervy.
We were watching the first series recently, and it has a charm, a kind of amateur charm. At that point we didn't involve ourselves technically at all - we just messed about and told our jokes - and it looks a bit like that.
But I think our humour is exactly the same today. Only, we've made rules now. We've said we are not going to do prosthetic make-up scenes, because when they take it off half your face comes off.
Men would find it much harder because men have such odd personal relationships with each other. They don't really emotionally connect, whereas women do. I think women become very close.
There were a lot of areas we didn't cover that I'm hoping to cover if we do some specials. One is to see more of Patsy's home and her home life, which is just the saddest thing.
