CSI: Crime Scene Investigation, Season 6

Hodges:
All the hairs lifted off the victim's clothes were consistent with each other. There's a sample under the scope. The root is shaped like a spade which is indicative of canine and the scale pattern is consistent with a golden retriever.

Sara:
Oh, yeah the victims have a golden retriever.

Hodges:
Well if you cracked that mystery at the scene, you would have saved me a lot of time. [sighs] I've been working like a dog.

Nick:
You know studies have found that pet owners have lower stress levels, you should, you should check that out.

Hodges:
Well, I had hamsters when I was growing up. My mother hated them she said they stank out my room. But I just loved to watch them spinning on their little wheels. One day I came home and they were gone. Somehow they'd gotten out of their cage.

Sara:
How much did your mother hate them?

Hodges:
They ran away.
