Hi Bathrobe,
Actually, there's nothing odd about this at all. It is no secret that Google takes into consideration the incoming links to a site as popularity and the use of the anchor text as the topic of the site.
The reason is, you are leaving comments in blogs with your url and the anchor text as bathrobe, as in this post
http://www.languagehat.com/archives/001873.php
There are obviously more blogs similar to this so Google thinks that because you have many different sites linking to you with the anchor text bathrobe, your site is about bathrobe.
If your anchor text(comment name) was "bird species", then you would be on the first page of Google for bird species.
