I hate PE

Growing up, my least favorite subject was physical education (PE).  I recall the 50 meter dash one day during PE class.  I don't recall what time I ran it, but I huffed and puffed with my legs running as fast as possible underneath me until I came across the finish.  The instructor told me, I got a, "C."  Like many other things in PE, I mostly came up with "C's" despite all of my effort.
