When I was growing up, the hour between when school let out and when my Mom's car hit the driveway was perhaps the most dangerous hour of our day (surpassed only by the hour when Dad found out about what we had done). You've heard about the dragging out mattresses so we could jump off the roof. The way we stretched the phone up to the roof so when our neighbor called our Mom we could "prove" to Mom we were in the house ("Crazy Nora!").
One day, after Batman was over of course, my brother Skip offered my brother Rod "a hundred bucks" if he ran around the block naked. Of course he didn't have a hundred bucks. This was around 1977-78 and the kids in our world didn't have more than the 10 cents needed for the ice cream man.
