  Only getting 2 ways to solve it brings us back to russian jokes: A soviet maths prof finds out he'd make more money as a labourer in the shipyards, so after more than a few carefully-distributed bottles of vodka he manages to change profession. A month or two working in the yards, and he sees a notice on the bulletin board offering a bonus to workers who sign up for a special "maths for the proletariat" evening school course. Figuring it's easy money, he signs up, brings a novel, and sits in the back of the class reading instead paying attention. Then the prof calls him up to the brownboard, and asks him for the circumference of a circle. Suddenly, our ex-prof blanks. Frantically he scribbles and scribbles on the brownboard, only to wind up with ... -2πr. No, that can't be right, but what went wrong? Just when he's about to crack trying to figure out his error, he hears a friendly voice from one of the front-row students: — Psst, colleague, swap order of integration!
