Dear Bad-Assed Kids:

"I suppose you deserve some gifts for your improved behavior this past day or so, in addition to how well you're all doing in school.  However, to make up for the fighting and bickering, I require that you open your home, as well as your hearts, to a poor lonely animals who had to spend Christmas in the shelter.  I'll be watching to make sure you provide a loving, safe home.

Mister C.

PS--You guys owe me BIG.  See you in November 2012--Todd"

This might actually work . . .
