Amy entered the console room to find the Doctor gleefully setting coordinates.

"Where are we going?"

"To visit a friend," the Doctor said, "he's blue."

"Oh, I'm sorry to hear that."

The Doctor looked up in surprise. "Oh, no, not blue melancholy, blue pigmentally."

"Pigmentally? Is that a word?"

"Dunno. I once knew a doll that was pig mentally. Nasty little bloke, he shot a dragon at me."

"A dragon! Weren't you crushed?"

"Nah, we hid behind the table."

Amy stared at the Doctor, then scowled. "I wish you'd quit pulling my leg."
