Udderly syncronized

Brandon at TextURL has spotted two cloned cow udders, visual representations that look and say pretty much exactly the same thing. A badlandian pair as good as any. I'm sure there are more of these udders though - can you think of any?

Now, I'm not really worried about which came first. I'm sure it's just a brain sync–or at least a brief-sync. After all, the solution is a fairly elegant way to visually demonstrate the key promise of "fresh dairy products." Kudos to both creative teams for finding a simple solution that distills the promise down to its essence.
The problem I have is larger than two similar looking ads. It’s the hundreds of visually similar ads I see when I review awards shows, design journals, and ad-blogs.
