I have to admit, I've been tempted myself. My In-laws LOVE to start talking in the beginning of a movie and ask each other "Who is that? What else did they do? I know that voice...that's not ----- is it?"...drive me crazy.
On the other hand I worry about the kids messing with it, so I plan to have it permantly closed when they are old enough. I know some Zombie Apocalypse nay-sayers will frown on the ruining of any weapon...but I must balance their well being and welfare vs. the repelling of an attack by the living dead.
