- Phil Diffy: I'm not getting all goofy over some stupid 2003 girl!
- [pauses]
- Phil Diffy: She's not stupid.
- Barbara Diffy: Phil, I'm very disappointed in you.
- [Lloyd leaves the room]
- Barbara Diffy: Even though that was a really sweet thing you did for Keely.
- Phil Diffy: Yeah, but I didn't mean for the whole family to get stuck here.
- Keely Teslow: Maybe it was meant to be.
- Phil Diffy, Pim Diffy, Barbara Diffy, Keely Teslow: [singing] Oh robo-tree, oh robo-tree / You're programmed just to thrill us / Oh robo-tree, oh robo-tree / It's Christmas, please don't kill us / We didn't mean to make you frown / Release our kids and put them down / Why didn't we buy astro-tree / It's guaranteed not to kill us / / Or your money back.
