"Hi, I'm the older child who lives in this house...."

Let me see if I get what you are telling me here, lady--

You like to watch bottom-feeder crud featuring zombies wielding chain saws, but you are afraid that if your KIDS watch what Mommy likes to watch, they'll get nightmares.  So you need to be the "boss of the TV" and block the stupid junk you watch from your impressionable kids.

I have a rather neat idea: How about taking this moment to re-examine your own tv viewing choices?  This MIGHT be a good time to ask yourself "why am I watching stupid, pointless brain flem?  Is it because I'm an Adult and I can?  Or am I less of an adult than I think I am?  I mean, thirty years after the Bloody Biker Type became the hackneyed symbol for the unstoppable lunatic, I still think he's Really Scary."

Seems to me that the wrong person is the Boss of the TV in this house.
