Rent Disney movies and hide the “Grown-up Toys”.

Then, wake them up before their parents come home, give them some Mt. Dew, marshamallows and chocolate chip cookies. Then send them home jittery, wired and wide awake.

Unless you want them to come back. In such case, feed them turkey, milk and read them stories. A dose of children’s Motrin works too, in case they have a “headache”.
