George Weasley

— How much is this?
— Five Galleons.
— How much for me?
— Five Galleons.
— I'm your brother!
— Ten Galleons.

I solemnly swear that I am up to no good.

— How do you feel, Georgie?
— Saint-like.
— Come again?
— Saint-like... You see, I’m holy. Holey, Fred, geddit?
— With the whole wide world of earrelated humor at your disposal, you go for holey? Pathetic.

— Probably a right sight better than he normally does.

— So a genius like Dumbledore couldn't possibly be fooled by a dodge as pathetically dimwitted as an Aging Potion.
— But that's why it's so brilliant.
— Because it's so pathetically dimwitted.
