Mark Twain once suggested a method of dealing with children like this: place them in a barrel and feed them through the bung hole.
At the age of 14, drive in the bung.
(Yeh, yeh, it’d never fly in today’s society–or in Mark Twain’s for that matter. Doesn’t mean it wouldn’t save a lot of trouble down the road… )
