Our two boys received as a gift a "Kreepy Krauly" toy oven, a small
oven used to bake plastic bugs. The boys prepared the first tray of
bugs and slid it into the oven to bake.

The younger one asked his older brother if he could look through the
clear plastic window at the top of the oven to watch the baking in progress.

"No," the older brother replied, "you don't have the right kind of
eyes. It says right here that you need adult super vision."
