I got a real one for ya that my 6 year old son asked a few weeks ago.
"Daddy how did you and Mommy make me?"
"Ummmm (formulates birds and bees story for 6 year old), well I planted a seed in Mommy and it grew into a baby and that was you"
"Oh ok, did you have to dig a hole to plant it?"
"Yeah, I guess you could say that"
