I have an elbow that bends the wrong way, and I'd do things like stand in an elevator and the doors would close, and I'd pretend that my arm had got caught in it, and then I'd scream, 'Ow, ow, put it back!'
I got a tiny part in a play, auditioned for another one and got that as well. Not only that, the first finished on the Saturday and the other started on the Monday which is like an actor's dream!
