The Faculty (1998)

Continuity mistake: Mr. Furlong pushes Zeke into the fishing tank and it breaks, soaking him from head to toe with water. Moments later they are walking out and he is dry.

Stan: Come on guys, this is nuts.
Delilah: Then leave, Stan. Why are you hanging around? Go win a Pulitzer.
Stan: Blow me, Delilah, 'cause I'm sick of you're shit.
Delilah: Well, then get the fuck out of here and take your little freak dyke with you.
Stokely: Fuck you, tit bags.
Casey: Will everybody calm down, please?

Trivia: In the beginning of the movie, Marybeth asks a girl with a piercing where the office is. That girl is actually the director Robert Rodriguez's sister, and she has a tattoo in the same place where George Clooney had in From Dusk Till Dawn, another of Rodriguez's movies.

Question: In the scene where the main characters are talking about their peculiar behaviours i.e.- "Stokely, since when did you start liking boys" and "What, Delilah, you haven't gone without hairspray and contacts since birth". Can anyone please tell me what Delilah means when she says to Casey- "And Casey, since when did you become Sigourney Weaver?" I have never understood what it means but I think it might have some reference to the movie "Alien".
