When they filmed the movie ‘Van Helsing’ in Prague they needed one hundred couples who knew how to ballroom dance. Everyone thought this was going to be difficult to set up, but it turned out that literally every extra they hired could waltz. Back in Soviet days, the country didn’t have a lot of money for sports equipment, but every school had a record player. They taught the kids ballroom dancing for the Physical Education requirement.

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.

Clearly, the system working as intended.
