Eventually, the climax of the show approached. The lights dimmed and the backing track started to play the opening bars of One-Thumb, Two-Thumb Good. With the loud burst of the cannons shaped like the claws of an enormous bear paw, Doodah landed back on the stage.

‘Dr Don’t Know,’ she said to herself.
