To graduate from my (American) high school, you needed a given number of gym points, and you were given one gym point per day of gym class. But, I learned, you earned one and a half gym points per day of dance class! I figured this was a great scam: I already hated gym class, so I'd get my points out the way faster.

Fast forward a couple of months, and I'm working harder than I ever was in gym class, I'm enjoying myself more, and I'm hanging out with girls in leotards first thing every school day. There was literally no downside.
