"Kimber, what's that red button for?"
"What red button?"
"The one on the side of your house."
"Oh. That's my naughty trap."
"What's a naughty trap?"
"Well… if you push the red button, poison darts fire out of those little holes right there, and they stick in your skin and paralyze you so you can't move until the naughty police can come."
"What if the police don't come?"
"Then you die a slow and painful death and the sparrows eat your eyes out."
Sometimes I tell them it's a release button for man eating tigers or the trigger for an atomic bomb that will blow up the entire city. Depends on the age group.
But they always push it. They stand there, thinking about it for a while–but they always push it.
