deleting a thread we started

There is a thread that I started back in April 06, and everytime someone googles my username that thread, and only that thread shows up in the search, and I want to know if I can have it removed? It wasn’t of any <em>real</em> value to the point where it would be of a disservice to others to have it removed, it was a question about dating and relationships, and I really just don’t want it to appear when people google me. Mods? Anyways to get it taken down?
