I can't wait till my son tries to take me down a notch; he's only five.
Wait, he already does.
But I got him: read him all about Greek myths and the Minotaur, till he was afraid to go upstairs by himself.
Course, the wife was none too impressed.
As the parent of a just-turned-six year old boy, I question the wisdom of any strategic decision that would make said child even less likely (when mathematically possible) to remain in his bed when put there.
