Sgt. O'Riley quotes from CSI: Crime Scene Investigation

'Sara: So, ladies of the wedding party, you get a free course in the forensics of sexual intercourse. Secrets of our trade. Lynn, when you had your exam for sexual assault a SART nurse makes a clock like this. (turns around and picks up a piece of chalk to illustrate on the blackboard) This is the vagina. It does tell a monologue. Some bruising is normal when sex occurs. Injuries at 11:00 ... 12:00 or 1:00 indicate consensual sex or what we would call "avid." Injuries around the dinner hour ... five, six, or seven, indicate forced entry. The woman hasn't done anything to help her partner thus sustaining serious bruising.

Grissom'

Hey, stop! Evidence! (Det. O'Riley stops and changes his course, staying off of the main floor and on the sides of the room)

Grissom'

You guys will never get it, will you?

(Seeing a couple officer's throwing up)
