A screwdriver can't even given them a paper cut," the Doctor said, before holding up his hand to stop her for interrupting. "But, in a contest of putting up cabinets and shelves, the screwdriver wins every time.

And if they still catch us....well, I guess we'll be able to use our wit and laugh about it."
