Stuff and junk or whatever

This clip from Futurama has stuck with me since I origianlly saw it. I use the line in my profile on social media. I’ve also realised I don’t quite get it right.

It’s from a season 2 episode called Put You Head on My Shoulders and the relevant passage from the transcript is below:

Amy: Yeah, and if you were the Pope they'd be all, "Straighten your Pope hat,"
and, "Put on your good vestments." [Fry laughs then Amy joins in.] You know,
Fry, it's nice to find someone I can talk to about stuff, and junk.

Fry: Yeah, it's like we feel the same way about junk and stuff, or, whatever.

    [He smiles. She smiles back.]
    [Scene: Mercury Surface. Later, the sun is setting and the Septuple-A
recovery truck arrives. A man gets out and sees the car hood is steamed up. He
laughs, rubs off the condensation and peers inside. Amy and Fry each hold a
hand of cards. The man sighs disappointedly.]
    [Cut to: Amy's Car. The recovery truck tows it.]

Amy: So while they're towin' us, you wanna do it?

Fry: Yeah.

Wouldn’t the condensation be on the inside of the car hood though?
