If she knows them, she'll likely respond, and since she would likely like Ghostbusters enough to know the obscure line, then shes a keeper.

If she doesnt know it, but may still be interested in your profile, she'll respond asking what you are talking about, and then you can say you were trying something different. Trying something different might get her attention to keep talking.

If she doesnt know it, and isnt interested, she wont say anything back. And you dont need people who dont like you AND Ghostbusters in your life.
