During the opening scene, the fighter with the blue and yellow trunks has his opponent in the red and white trunks in full guard (his legs wrapped around his body). But in the next shot, the fighter with the red and white trunks has the mount position on his opponent (he is sitting on top of his opponents torso).
The shorthand Jane uses in the notebook to help catch the criminal is known as the Theban or Witches alphabet.
Jane: (to Merriman) Either you're a genius manipulator concealing your complicity in the case, or you're... a dimly lit clown. Which is it?
Floyd Benton: Ah. Police officer.
Jane: How'd you know?
Floyd Benton: Police and fine women always think they have a right to be wherever they're at, and you ain't no fine woman.
Jane: Your fighter looks bigger and stronger. Shouldn't he be winning?
Floyd Benton: He's slower and dumber.
Beatriz: We've been together since I'm 13, married since 17, 4 kids. You think I don't know what's going on? He's a professional athlete. I blame it on the women. Men don't know any better.
Manny: Baby, I never--
Beatriz: And you know what? Manny's good. He doesn't go all crazy, but we do have the nurse at the physio clinic, the two waitresses in Vegas, the girl at Len's club...
Lisbon: You gotta feel for the guy. He lost his livelihood.
Jane: Meh. Lost a life of getting hit in the head, but he got his marriage back. Seems like a fair trade to me.
Lisbon: Aren't you the romantic.
Jane: Makes the world go round.
Lisbon: LaRoche. You're supposed to inform me when you talk to one of my people.
LaRoche: That's not a right. That's a courtesy we extend on occasion.
Lisbon: Well, in the future, I'd like you to extend that courtesy to me.

This quote is from Star Wars. Obi-Wan Kenobi, Luke Skywalker, R2D2 and C3PO came from Luke's uncle Owen's waterfarm, to Mos Eisley in quest of a spaceship in order to rescue Princess Leïa from Vador's hands. Stormtroopers verifying travelers' IDs stopped them, and Obi-Wan used those words as part of a Jedi mind trick to get them past.
