It's been a while since I've been bowling, but these Batman bowling balls and pins from Bowlers Deals make me want to pick it up again. There are various balls and pins featuring Batman (who has three different designs), Robin, Batgirl, Joker, Penguin and Bane. Most of them have different images on the front and back, too. There's also a bat-bowling bag, and you can buy the pins individually to create a uniform set of mix and match.
