Fred Weasley: It's the secret to our success.

George Weasley: It's a wrench giving it to you... believe me...

Fred Weasley: But we've decided your needs are greater than ours. George, if you will.

George Weasley: I solemnly swear that I am up to no good.

Harry Potter (reads the appearing words): "Messrs. Moony, Wormtail, Padfoot and Prongs... are proud to present the Marauder's Map."

George Weasley: We owe them so much.
