- [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.

- Ringmaster: [quoting "Romeo & Juliet"] ... From forth the fatal loins of these two foes / A pair of star-crossed lovers take their life / Whose misadventur'd piteous overthrows do / With their death, bury their parents strife.
