Quote from Beverly in The Proposal
Adult Adam: [v.o.] Not surprisingly, my mom sensed something was up.
Beverly: [gasps] Geoff and Erica! Aah! [giggles]
Erica: What's happening in here?
Beverly: Just doing my jazzercise.
Erica: In Barry's room? With no music?
Beverly: Silent jazzercise. It's for librarians and mimes.
Erica: Well, I'm glad to know you're part of a vibrant community.
