Yes, there is such a thing as championship whistling! http://whatstrending.com/hot-on-youtube/21053-what-it-takes-to-be-a-world-champion-whistler
I hear there was a scandal with professional arm wrestling being rigged a while back. People paid to throw matches.
Ever see the movie "Over The Top?" Some truck driver (Sylvester Stallone) has has a strategy he unleashes upon the arm wrestling world to win the big money and his kid's heart. Let that sink in......strategy in arm wrestling. It's like strategy in bowling - nobody has ever came up with anything better than knocking all the pins over. Just sayin'
