[Stella & Mac are investigating a case at a circus]
Detective Stella Bonasera: Until now I never really believed people were double-jointed.
Detective Mac Taylor: They're not. There's no such thing as double-jointed. It's just people with very loose tendons and muscles.
Detective Mac Taylor: The stereotype is that kids run away from home to join the circus. Where do kids already in the circus go?
Danny Messer: Blood from the apartment was hers. Unfortunately, she's still a Jane Doe.
Sheldon Hawkes: [showing a wedding ring from the corpse] Actually, Mrs.Jane Doe. She's married.
Danny Messer: Obviously not for the cash. It's a tiny rock.
Don Flack: This is New York, Danny. You can have anything delivered - groceries, dry cleaning. I'm jonesing for a pastrami sandwich at 3:00 in the morning, I call Andy down at the deli - boom, done.
