That'd be the first time for me. Then again, I've only been around here for 10 years or so, so what would I know?
I've seen the rumor posted by an individual or two. Multiple rabid posts on the topic? Never.
I’ve been here for about 10 years, too, and I saw plenty of insinuation about Chelsea Clinton while she was still a minor. Since you seemed to miss them, try “chelsea web hubble site:freerepublic.com” in Google.
