JESS: [to Mrs. Kim] Baseball bat?
MRS. KIM: Cricket.
Cricket, a game played with a bat and ball with two teams of eleven players. Originating in England, it is played in the UK and Commonwealth countries around the world, but is not a widely known sport in the US.
Cricket bats are heavier than baseball bats, which might be why Mrs Kim favours one for a weapon.
