@CaptainJack_Harkness Jack requested that I do the Sonic Screwdriver argument. ... well, here it is!

Doctor: Go now! And don't drop the banana!

Jack: Why not?

Doctor: good source of potassium!

Jack: Who's got a screwdriver?

Doctor: I do!

Jack: Who looks at a screwdriver and thinks 'Oh, this could be a little more sonic!'

Doctor: What, you never been bored? Never had a long night? Never had a lot of cabinets to put up?

Doctor: C'mon, we're not done yet. Assets! Assets!

Jack: Well, I've got a banana and in a pinch you could put up some shelves.
