When I was in grade one we measured everyone's height and weight, and put it all on a big change t which hung in the corridor for a month....this would uav been mid 70s. So I'll thought it out ideas like this are not a new thing.
(This was when I realized I was bigger than my peers. My best friend and I were both ~60lbs, everyone else around 40. Since we were the fastest runners, best red rover players, and I had a bullet proof male ego, I concluded everyone else was too small and we were just right. For a more sensitive kid it could have been far worse.)
