Non-Scents and Rubbish!

Well, there's a new study out, and you know how much I love these studies. And, it shows that when asked to sniff male testosterone (which kinda grosses me out to begin with), homosexual men's brains responded more like women's brains. Now, I'm not about to touch this subject, except it did give me an idea.
You know how you're always seeing these wives on daytime TV (ie Jerry Springer, Oprah, etc.) who find out after years of marriage that their husbands are gay? And, of course, they then have to come on television and proudly talk about how humiliated they were. You've seen these women, I'm sure. They describe every gory detail of their husband's outing, usually in some local park or school, while the audience, in its typical dignified manner, hoots and hollers and eggs them on to tell more.
Well, why not invent some sort of homomometer? So, let's say this guy asks you out (we're assuming you're a female in this scenario), and you want to be sure that you're not going to end up on the Jerry Springer show in five years or so. All you do is have him sniff into the device and it tells you instantly - gay or straight. Maybe it could even have some sort of dial that tells you how gay or how straight, because maybe the really straight guys are the ones who end up on Jerry Springer for beating their wives senseless when she burns the toast.
Now, I may be going out on some sort of genetic limb here, since I have absolutely no idea what I'm talking about. I'm just sort of thinking out loud. But, I believe there really could be some sort of commercial application to a device such as this.
And, while we're talking about those inane daytime talk shows, I wish someone would do a show examining those emotionally-troubled audience members who applaud at the most inappropriate moments. You know the type I'm talking about. The low-life guest will say something like, "So, Jerry, I caught my husband with the mailman (no offense to the USPS)." And, the audience will go wild. "So, Jerry, I got back at him by setting the house on fire." (more wild applause)
Then some idiot in the audience will be given the microphone, and she'll shout out, "I'm offended that you get upset because your husband was with the mailman. My husband works for the Post Office. What do you have against postal workers?" And then the audience will go crazy applauding that statement. They'll applaud anything and everything - on both sides of the issue.
What's with these people who come to see these shows? Well, I guess I really answered my question with my question. What we really need is a device that could predict if your future mate is someone who is going to really love watching the Jerry Springer show. Now, that's the type of person I'd hate to end up marrying.
