A website called Is My Baby Gay
offers to inform you of your child's sexual preferences for a fee of only $19.99. They direct customers to print out a circle on a piece of paper. You're then supposed to apply the tongue of your baby to the center of the circle for 15 seconds. You mail this piece of paper to the "Is My Baby Gay" testing center, and they promise to get back to you with an answer within two weeks. If they turn out to be wrong, they promise that they'll refund 150% of your purchase price.
At first I thought this had to be a joke, but apparently they really will take your money. They've set up a paypal payment system to do so. Which transforms this from a joke into something more like a scam. [Note: I didn't actually try to pay them anything, so perhaps at the last minute they decline to take your money... but somehow I doubt it.]
On their front page they've included a phrase which is apparently their legal escape clause: "Results are intended for entertainment purposes only."
I'd like to think that no one would actually take this site seriously and mail in their baby's saliva sample. But there's probably someone out there dumb enough to think this might be for real.
Even dumber would be someone knowing there is no such thing as a saliva test for sexual preference, but paying $19.99 anyway just for the fun of getting some bogus results.
