The worst gym class I ever had was the day we had a substitute; we had to run laps for the warm up, and the substitute pulled out a new rule: “No Passing!”

So there we are: I’m plodding along, at about the speed of molasses running up hill, and trailing behind me are all 30 of my classmates, grumbling and cursing like a surly caboose.

I am *so* glad she was just a substitute, if I had to do that every gym class I would have shot someone.
