From Natter:

Steph L: I have 4 rooms and a nomadic roach population.
Aimée: Do they use ants to move their stuff from room to room?
Steph L: I strongly suspect so.
Aimée: I think our ants use the dog. They tempt him with treats.

Context is for wimps.

JON B: I liked the blood, but I respect your concerns.

Shrift in Firefly:

Okay, ita is the third Death Star that was never built because leaning on her too hard will probably make her "accidentally" break your nose, and she'd shishkabob the Ewoks, and "Death Star" is too cool a name to waste on shoddy empire contract work.

Noumenon in Firefly:

OH MY GOD! ita is a moon on one of Tim Minear's shows! She's DOOMED! This is gonna be worse than Alderaan!

(this should be the prefix to the above.)

And to make it a trilogy, right after Hec's quote:

DXMachina: That's what happens when you always go with the low bidder.
Madrigal Costello: I can just see all those Imperial workers slacking off, spending their days nattering online about whatever passed for Buffy in their day, since it was a very long time ago, I suspect they had a primitive version of the show.

And MM with the follow up...

Something like "B'oofah the Jedi Slayer".

And the nattering would be something like. "I can't believe Jo'ss is having B'oofah sleep with that soulless Jedi. That's so lame. What about Anjell? B'oofahnAnjell4rceEvah!!!!11!!!!"

The more I think about it, the more I think we need the whole thing.

Ling Mao: ita, you rock!

PMM: she's not a rock, she's a moon!

Miracleman: That's no moon...that's a space station!

Sorry. Sorry. Geek reflex. Sorry.

shrift: But ita is so the Death Star!

Madrigal Costello:

Which one? The first one which blew up if someone just leaned on it too hard, or the second that was capable of mass destruction even with a big piece missing, and required the death of several ewoks to destroy?

[edited for attributions]

Betsy, the first one of your '??'s was Ling Mao (well, specifically in this case - pretty much any of us said it one time or other or constantly), and the second was PMM.

And, again, from "Firefly", without the context:

Theodosia: I was onboard with Betsy for the Hyena Train.

Betsy Hanes Perry: This is the Hyena Laughter train, not the Hyena Sex train, right?
checks ticket nervously

Aimee: No! Never! See, one of my "things" is I am a HUGE HUGE HUGE animal person.

Billytea: Then rhino's definitely the way to go. You'll have to promise to clean up after it, though. Trust me on this - there's a reason "I'll clean up after your pet rhino" never makes it into the wedding vows. Some things are just too far above and beyond the call.

Shawn: I guess I have to pass the bar instead of repeatedly going inside, don't I?
