How well would a "school shooting chocolate calendar" sell?

You know the common christmas calendars for decembers that have 24 doors and have a small piece of chocolate behind each?
You could have a school massacre themed calendar for the whole year with, let us say, 5 doors a month, and each time you hear or read about another hero having his own little schoolyard purge, you would open one of the doors for the month, and get a bit of chocolate.
That way, you could turn the annual bloodfest into something positive! Yeah sure, some more kids died, but at least you got your chocolate!
Those would also make awesome gifts for any NRA member or gun owner you know.
There could even be special promotions, like 2 for the price of 1.
