CSI: Crime Scene Investigation, Season 4

Warrick:
You know, Sam ... that word that you wrote on the floor ... you know, that's a really bad word.

Sam Abernathy:
I hear it all the time. My grandma says it. (strikes a match and puts it out in the mug.) My mom says it. (strikes another match and puts it out in the mug.) And my sister says it. (strikes another match.) Well... she used to say it. (blows the match out and watches the smoke rise up from the burned match. He drops it into the mug)
