Quote from Rachel in The One Where Chandler Can't Cry
Rachel: So did you guys hit it off? Ross: I guess so. Rachel: So did anything happen? Because rumor has it you guys shut the drapes. Ross: No. No. Nothing happened. I shut the drapes to show her slides of my favorite fossils. Rachel: Oh, slides. So really nothing happened. Ross: Something could've happened. All right, she really dug my slides. And she was definitely giving me the vibe. Rachel: Was it the "Please don't show me another picture of a trilobite" vibe?
