I found this worksheet about exercise in a stack of my papers from first or second grade, and my eyes bugged out for a moment before I broke down laughing.
I can only assume that my teacher had the same reaction (and this must have gotten passed around the teachers' lounge). I noticed that my last answer here is the only one (on this page or the next) that didn't get any corrections or comments.
As I recall, it certainly was a lot of exercise!
