Elf On The Shelf Life

As the holidays approach, some parents use an Elf On The Shelf doll to convince their gullible, naughty kids to behave themselves.
Christmas comes and goes, the kids unwrap their presents, and the elf goes back in his box until the holidays come around again.
During this time, who watches the elf? What keeps the elf from misbehaving and causing trouble?
Chicken wire and duct tape usually do the trick.
I know one family that sticks the elf in a Tupperware, fills it with water, and freezes him. Just to be safe.
They don’t get invited to many parties.
