Does anyone know sign language and watch CSI.

At the end of last night’s episode, Grissom told this woman something about himself in sign language. What did he say (sign)?

Am I the only one who watches this show?

Don’t know ASL, but I’m wondering about that weird lie detector that told from his brain waves if the testee had seen the image in a photograph before. Sounded like bullshit to me.
