Lorraine Baines: Dammit Biff, that's it. I'm leaving! Biff Tannen: Oh, so go ahead. But think about this Lorraine, who's gonna pay for all your clothes, huh? And your jewelry, and your liquor? Who's gonna pay for your cosmetic surgery Lorraine? Lorraine Baines: You were the one who wanted me to get these-these things! If you want 'em back, you can have em. Biff Tannen: Look, Lorraine, you walk out that door and I won't only cut off you, I'll cut off your kids. Lorraine Baines: You wouldn't! Biff Tannen: Oh, wouldn't I? First, your daughter Linda, I'll cancel all her credit cards. She can settle her debts with the bank all by herself. Your idiot son Dave? I'll get his probation revoked. And as for Marty, well maybe you'd like to have all three of your kids behind bars just like your brother Joey. One big happy jailbird family. Lorraine Baines: Alright Biff, you win. I'll stay. Biff Tannen: [to Marty] As for you, I'll be back up here in an hour, so you better not be!
