Futurama advertising on Fox Kids?

I just happened to turn on the TV to Fox Kids Saturday Moring Cartoons (don't ask me why) and noticed that Fox is advertising Futurama between commercials for Froot Loops and Willy Wonka candy! Is it a normal practice of Fox to advertise programs geared toward a more adult audience like Futurama to kids? A show about 25-year-old with an IQ of 105, an alcoholic robot, and a busty femme isn't exactly the most perfect show for kids.

If Fox can (and does) advertise their show (Guinness) where a guy is pounding a nail into his scull and another guy is eating a can of worms, and America's most shocking, grosse, dangerous police crash arrests (during Simpsons and Futurama), I don't think they think twice about advertising Futurama during kid's shows..

You "just happened to" turn it on, huh? ;) Fox probably figures that there's a significant number of mature animation fans who also "just happen to" check out the children's cartoons too, you know, just out of curiosity or something. Either that or their marketing people can't tell one cartoon from another.... Do they advertise "Family Guy" on Saturday mornings too?
