Papa John's Dual Layer Pepperoni TV Spot, 'Ghostbusters: Best Customer'

When there was something strange in the neighborhood, they called Papa John instead of the Ghostbusters, which turned out to be a mistake. Even though there's mass hysteria with people running and screaming, while Slimer chows down on boxes of Pepperoni Dual Layer Pizza, Papa won't bust him because he happens to be his best customer. You can see more of Slimer's antics in the new "Ghostbusters," in theaters July 15.
