MYTH # 1: You can throw a ball with a pin in the gutter.
CONFIRMED: A bowling ball must not come in contact with anything before hitting the pins on the pin deck. If the ball hits a pin in the gutter, otherwise known as deadwood, the delivery counts but the resulting pinfall does not count. A downed pin on the lane is also dead wood. USBC recommends dead wood is removed prior to making a delivery so you don not lose your opportunity to score. Illegal pinfall can also occur when pins ricochet after hitting deadwood
MYTH #2: You cannot substitute a bowler during a game.
BUSTED: Rule 107c-10 allows the team captain to replace a player during a game. The player cannot return to that game but may bowl any other game in the series.
