Watched an old episode of "Dennis The Menace" from 1963 today, and it was about Dennis' elementary school basketball team. I'm not as knowledgeable as some of the guys on the rules back then (assuming real lower level school teams used NF rules) but I did see the following:
*players had numbers only on the back of their jerseys
*many players had "illegal" numbers
*one player played barefoot (not kidding)
*they played 10 minute halves
and worst of all - the referee (there was only one) wore khaki pants WITH A BELT!!!!!
