Lucille: It's a pity those poor girls can't have their whole family together.
Marty: Oh, Ma, please. Don't start.
Jeff: Don't use that tone with Mother.
Marty: There was no tone.
Jeff: Tone.
Marty: There was no tone! Tim, what do you think?
Tim: I think all these wrenches are metric.
Lucille: All I'm saying, Marty, is that it's a shame that you couldn't have worked something out, at least for the holidays. Right, Tim?
Tim: I wonder how big my head is in metric?
Marty: Look, Nancy's the one who's being impossible. And there's nothing I can do about that.
Jeff: And so, to compensate for your inadequacy, you lash out at the woman who gave you life. You should be ashamed. Shouldn't he, Tim?
Tim: Huh? Now, that's one sizable melon. Look at that baby, huh?
