My daughter and I were playing softball and on the next field were a bunch of guys playing cricket. She asked me Why is Cricket called Cricket? I had no idea and figured this was a good place to find out.
Perhaps from a Flemish dialect of Dutch met 'with' de 'the' krik ketsen 'to ricochet', i.e. "to chase a ball with a crook".
The Online Etymology Dictionary explains it this way:
1590s, apparently from O.Fr. criquet "goal post, stick," perhaps from M.Du./M.Flem. cricke "stick, staff," perhaps from the same root as crutch.
