"Doctor."
"Yes, Rose?"
"I'm not sure that I want to ask..."
"What is it?"
"Okay, here goes...why is there a swimming pool in the library?"
"Oh! You found the pool! Been looking for that for ages! Thought I'd lost it!"
"You...lost it? How do you...never mind...whys it in the library?"
"Contrary to popular belief, I actually don't know."
"You don't know? Fat lot of good you are!"
"Oi! I try my best."
"Well, I just dropped a book in there, and the pool cleaner sucked it up and then spat it back out at my head. Is that normal?"
"..."
"Why are you laughing at me?!"
"..."
"Stop it! It's not funny! I have a big bruise forming on my cheek and my hair is wet!"
"..."
"Stop laughing! It's not funny! It really hurt! Your pool cleaner is completely savage!"
"Oh, Rose!"
"If you don't stop laughing right this second, I will throw the sonic into the pool."
"Now that's just mean!"
"Don't test me."
"..."
"How do you lose a pool, anyway?"
