Sometimes i wish i had godfather who was an escaped prisoner of Azkaban just so i could use that line of Harrys as an excuse to scare people into leaving me alone and giving me what i want. he'd have to be a wizard of course
Harry would never make fun of his friend like that though. He reserves his sass for those who deserve it. Ron feels insecure enough about the robes in the book. That said this scene is hilarious in the movie. But it wouldn't work in the book << Very true.
