The most counterintuitive fact, er... fib is this nugget:

"0% selected the right answer on this SAT question: Circle A has 1/3 the radius of circle B, and circle A rolls one trip around circle B. How many times will circle A revolve in total?"

You know how hard it is to get 100% of the people to do something? Don't insult our intelligence like that, or of SAT test takers in general.
