Sarah Thinks That She's Biff

Sarah got a perplexed look on her face, then said "First of all, they're not yours. They're mine, obviously. And second, _you're_ Sarah. I'm Biff, remember?" "What are you talking about?" Biff asked. Sarah looked him over. "You didn't bump your head or something, did you, babe?" "No! Sarah, come on. Stop messing with me. Tell me what's going on," Biff demanded. "Man, you got fucked up, didn't you? Maybe I should take you to the hospital. You must have bumped your head and forgot." She grabbed his arm, but he pushed her away. "I'm not the one that needs a doctor!" Biff yelled. "Sarah, calm down. Don't cause a scene," Sarah said. She really did think that she was Biff.
