[英文] CSI Season 5 Eposide 14

In a bar.
[Brad]: Hi, can I ask you a question? It's critical.
[Lori]: Okay.
[Brad]: Am I your type?
[Lori]: I am married.
[Brad]: Oh, yeah. Nice try. Ring?

Also, in this episode, I heard a phrase, "Fool around."
I used it before, such as "I am fooling around," when I am free and have nothing to do.
Once, when I said that to someone, I found he looks strange.
Untill today, I finally found another meaning of "fool around" is having extramarital relations with a married person. I decide not to use this phrase unless I have nothing to say.
