Nick: The semen sample I recovered is still being processed in DNA.
Greg (walks in): Not anymore. I'm done. And no jokes about me being fast in this department. The ejaculate outside the first girl's window -- spank high. Good news: It does have DNA.
Greg: I don't know. Ran it through CODIS, nothing kicked out.
Catherine: Well, it's possible this guy's so new he doesn't even have a record.
Greg: Well, I can tell you this about him: Really low sperm count. Sample hardly had any swimmers.
Nick: That's probably from excessive masturbation. Guy's outpacing his ability to produce ... (he looks up and finds everyone staring at him) ... sperm.
Warrick: You'd know it, spanky.
