CSI: Crime Scene Investigation, Season 8

Wendy:
Hey buckaroos, have you seen Catherine? Because I just got the results from that semen stain on Cody Latshaw's jeans.

Nick:
Come up with a match?

Wendy:
I did. I had to run an Ouchterlony test on it.

Greg:
So, not from a human donor?

Wendy:
No, no, bovine. (Nick and Greg look appalled) Yeah. I took a psychobiology class once and we studied a very interesting case. Okay, there was a guy who lived on a farm, and literally the only way that this guy could get sexually satisfied was when he was with livestock. (Nick tries to interrupt)

Nick:
Hey, that's okay, I'm good...

Wendy:
(growing more enthusiastic as she continues) Well, you see, apparently the whole thing started one ngith because he was in the barn and it started snowing, he was stuck in there and couldn't make his way back to the farmhouse so he decided that he would try and stay warm... well, with a sheep. (Nick just looks at Wendy) But then the horses were jealous, so, you know... And I think there was a cow in there as well...

Greg:
You know, I think we got the picture.

Nick:
I wish I didn't.
