Whenever I need to pedal really fast, I get the Wicked Witch theme from The Wizard of Oz going through my head--you know, "daNa-daNa-daNana, daNa-daNa-daNana, daNa-daNa-daNana DAAAAAAA".
This is even funnier because I played the Witch in high school. Oddly, I can't remember if I did the Kansas scenes or not; my primary memories are of the little flash thing I used to shoot fireballs at the Scarecrow, and how uncomfortable flying harnesses are.
