Yep. That's right. Wiffle ball. Or as my brother says "wiffle stiffle ball". It is very very fun. When I was little I came up with this little game called "Cluckers" don't ask me why, 'cause I have NO clue whatsoever. But to this day our backyard baseball diamond has been called "Cluckers Field-Home of the Marsh Rd. Maniacs!!!!"
