And where's Biff? You're asking for it. I don't know. Don't you have any idea? No! He could be anywhere by now. Marty, the entire future depends on you finding Biff and getting that book! I know! I just don't know where... [Lorraine] Stop it! Stop it, Biff. You'll break his arm. Stop it! Of course! I gotta go. I got one chance! My old man's about to deck Biff! Yes! Talk about dÊjŕ vu. Are you okay? Okay, everybody, let's back up now, huh? Let's back up. Everybody just back up. We'll give him a little bit of room, a little bit of air. It's okay. I know C.P.R. I know C.P.R. - What's C.P. R? - You! He's fine. Hey, did you just take his wallet? He took that guy's wallet. Doc, success. I got it. Thank goodness. Great, Marty.
