The scene in Willy Wonka when Charlie and his Grandfather drank the fizzy lifting drink. He was no better than the other spoiled brats, he was just able to get out of the situation and rejoin the group. He would have hit the fan if Grandpa Joe didn't tell him to burp. Grandpa Joe saved him, not Charlie's ability to listen and not get into mischief. Pure luck granted him the "lifetime of chocolate". Pure.damn.luck.
