The little signs have the middle finger sticking up. What an unusual way to target kids. The people who put them up were told to talk their way out of it if stopped by police. Well, now they have their opportunity to talk. Time Warner, the Hugh Corporation, is responsible. Just goes to show you, even the big boys are willing to break the law for free advertising. Jerks--

Not the brightest thing to do! It's not aimed at kids, but adults that watch cartoons in the "Adult Swim" time after hours.

Heh heh, I saw this in the news before I turned on the computer. "The little signs have the middle finger sticking up." Seems appropriate for placing in spammer's front yard facing the house. I wonder if any of these are going to be sold on eBay.
