OMG! This is the most wonderful thing ever:D I was watching Mary Poppins a few months back; it had been a long time since I had seen it last; and when she started pulling stuff out of her handbag I blurted out real loud "It's bigger on the inside!!" and continued to grin like a loon for the rest of the movie. And now I have a image of the Doctor and Rose having tea on the ceiling with Mary Poppins. :D
