The simple fact is: sex sells. There's blatant and hidden innuendo in every commercial from burgers to cars to Saran Wrap ("What do you want tonight, see through or red?"). You have only a few ways to deal with it: Change the channel, boycott the products, and write the sponsors. When enough people complain, they'll drop it in favor of something else. But if their sales increase, it's gonna stay on.
I did send a letter to Hardees. But it doesn't excuse the behavior.
