Below is a statue on the demise of Milo.  No clue about the inclusion of the lion.

@bocaholly and, apparently, the few others.  Sorry (I guess) for puzzling your cranium. I always remember my youth in the days of the Kennedy administration when I think of Milo.  In about our only involvement of physical education in school, we were given annual physical tests such as how many sit-ups we could do in a two minute interval (among other exertions).   My abdominal muscles were sore for weeks after that test which left me wondering what gain had I achieved from that national “datapoint.”

During the same interval, we were periodically paraded into the corridor and told to put our face across our forearms as we braced ourselves against the wall.  After pondering the consequences of that possibility for the five minutes of the drill, I raised my hand to inquire as to the next portion assuming survival of the initial atomic blast.  There was no such drill.  That night, my parents wrote a note requesting that I be offered reading time in place of the drill.  That went over big, but was ultimately successful.
