When I ride the front car of a roller coaster, the last words I say, while waving my hands in the air, as we chinkity chinkity chink, up the long hill, are: "Look at me ... I'm not holding on" ... then the car goes over the crest ... and instantly "WHAM" ... my both my hands slam the handlebar, in a white knuckle deathgrip, so fast that I sprain both wrists.
