[Biff is walking down the street when a basketball suddenly rolls his way. He picks it up claiming it for himself]
Basketball Kids: [rightful owners come up] Give us our ball back. Give us our ball back.
Biff Tannen: Is this your ball?
Basketball Kids: Yes!
Biff Tannen: Do you want it back?
Basketball Kids: Yes!
Biff Tannen: [throws the basketball onto an upper balcony of a brown house] Well, go get it! Ha-ha!
