The best thing about setting him up is seeing him miserably fail, because it is a dark-sided character and his humour really comes [out] if he�s being humiliated or if he�s got icing all over his face.
Then you see his humiliation and you see that fumbley-ness that he has, and that�s humour. I think it�s the way the writers play his character and put him in those certain situations, so it�s dictated by plot and story and movement.
