Everybody Poops at the White House

While I was reading a Yahoo! News story I decided to click on the "President Bush" link to see what Yahoo! would suggest as search results. The second link is http://www.whitehouse.gov/#everybodyPoops, which is of course a valid link, but I have to wonder where that bizarre anchor tag came from. (The anchor "everybodyPoops" is not present on the White House's web site, so the page displays as it would if you went to just whitehouse.gov.)

Don't know if this is Googlebombing (Yahoo!bombing?) but it made me laugh.
