TV Trope: Disaster Dominoes
Troy: What are you doing?
Annie: Ending this. [She sends a text] Leave me alone.
Troy: That’s so much worse.
Annie: See? She stopped. [The phone starts to ring] She’s calling him?!
Troy: She was born in the 80s. She still uses her phone as a phone.
Annie: That’s fine. It’s fine. We just won’t answer it.
Abed: Won’t it go to your voicemail?
[Annie answers & holds the phone out but the boys won’t help]
Britta: Hello? Blade?
[She hangs up. Troy & Abed stare at her]
Dean: … You did good.
Annie: I don’t know!
Abed: Change your settings so it doesn’t go to voicemail. [It rings again] Too late.
Annie: You guys, act like a carnival. Be a carnival - now!
Troy: … Step right up!
Abed: Ding, ding, ding!
Dean: Get your popcorn here!
Annie: [putting on a voice] Busy, babe.
Britta: Blade just wait!
Annie: [sending a text] I told you not to call me at work. [Britta answers] ‘I’m sorry I forgot, don’t be mad at me’? She’s whipped by an imaginary douche!
Dean: Hey, don’t knock it till you try it.
