I think that one of Tim's great qualities and abilities is in what seems like a thumbnail sketch to get something quite telling, very simply, when you're doing it or being in that thumbnail sketch, you don't feel that it's important.
I was always taught if you do something, face the piper. Try to make it right.
A question I get asked a lot is 'What is it like to play the straight guy all the time?' And I'm totally okay with it.
