There’s a rather clever and amusing commercial here for Trojan condoms. I won’t spoil any of it; just watch it. Also watch the “Making the Commercial” shorts while you’re there.
The story (which is on the NYT site somewhere) goes that CBS and Fox have refused to air it, despite the fact that their programming regularly includes a good deal of explicit sexual activity. Apparently it’s okay to show their audiences all sorts of violence and promiscuity but not to try to teach them some responsibility.
