My first thought, before considering the possibility of his own children, is that to find this out, he'd have had to confront the children for some reason. Which would be a scary occurance on their part.
I have the opposite problem. Small kids would always run up to me, grab my leg and yell "Daddy"!!!!
I'm black and I've had black, white, asian, and indian kids do this.
Their parents did not think this was funny.
63 - I can't imagine the kids were very amused once the realized their mistake either, also: white, Asian, & Indian? And you're black? What is this fuckery?
"Well hello there little kid, and what is your name?"
"My mommy told me not to talk to you."
-anything as simple as that and i wouldve caught on too. :)
Use it to your advantage. You can scare the crap out of all the kids for Halloween. Only about 7 months to plan your evil labyrinth, better get planning.
