Wow... There's a whole story here just waiting to be told.
I'd love to hear your take on it, James!
Hmmm. Dad with two bratty kids becomes a zombie and tries to eat their brains (probably succeeded in eating mom's) and finds the tables turned on him once again in spite of his rad-awesome zombie powers. The picture depicts his feeble attempts to get away before succumbing in a macabre recapitulation of what happened on normal Saturdays before he became a zombie.
James, you astound me.
