It is amusing to make a chart of the parents' intelligence (vertical) over the life of the child (horizontal.)
In the early years, the parent's IQ is at the highest - mommy and daddy know best. When the kid hits middle school, the parents' IQ drops to below average. During high school, the parents are complete idiots. But somewhere in the kid's twenties, the parents start getting smarter and they keep on getting smarter.
