10. Egg Knocking
Also known as egg tapping or egg jarping, egg knocking is a sport where two competitors tap the pointed ends of their eggs against each other to see which one cracks and which one "survives." The game apparently goes back to medieval Europe, but when it comes to modern-day egg knocking, Marksville, Louisiana, is uncrackable. Since 1956, local families have gathered at the courthouse square on Easter Sunday to battle their eggs. Some families even prepare months in advance, giving their chickens special feed in hopes of producing stronger eggs.
