The pigtail girl stands facing the spiky-haired man across the arena floor. "I bet 80 hours I'll win!!" she declares. "AGREED," the man replies. He thrusts his fist forward and shouts, "WE'RE GONNA BET ON 'ROCK-PAPER-SCISSORS'!!" The girl answers with a grin, "WHATEVER! I'LL JUST USE MY LUCK!" A close-up shows the man's sweating face as he thinks, "HOW CAN SHE BE SO CONFIDENT AT THAT GAME?" The girl responds calmly, "DOES THAT BOTHER YOU? WE BET THE NUMBER OF HOURS WE WANT, ANYWAYS, DON'T WE?" She continues, "YOU HAVE SUCH AN EXPRESSION ON YOUR FACE! IN FACT, I'M NOT PARTICULARLY SURE OF MYSELF..." She then explains the statistics: "STATISTICALLY, THE HAND'S POSITION THAT SHOWS MOST OFTEN THE FIRST TIME IS 'SCISSORS'... AND MORE, TO THE STATISTICS, YOU CAN ADD PSYCHOLOGY. AND IF WE LOOK ONLY TO THE PROBABILITY'S POINTS, I ONLY HAVE 1 IN 3 TO LOSE, AND 2-3 TO WIN! IN FACT, I HAVE CLOSE TO A 70% CHANCE NOT TO LOSE. THIS IS ONLY A QUESTION OF PROBABILITY AND PSYCHOLOGY. ROCK! PAPER!"
