"There is everything wrong with pears," the Doctor said as he took his seat next to Rose. "They're all mealy and flat tasting and blech. I'd rather have an apple. Apples are better than pears. Good thing that friend of your mother's didn't have any pears in his dressing gown or I might've called it a day then and there. Still can't believe he had a satsuma stuffed in the pockets, of all things. Now then, drink up. Tell me if I've gone horribly wrong or if I ought to start marketing banana tea to support myself in Pete's World. It may not be as exciting as my usual pastimes, but it may be an improvement over having to go to work for Torchwood."
