I'm sure other members of MyBlogLog have noticed this when they check their stats. Somebody does a Google search and Google calls up one of their blog posts as a relevant reference.
Sometimes the associations are weird. Today someone did this Google search: can body lice drown in the bathtub.
Google served up several sites, but also listed Mental Blog sixth with this entry: What's Bugging Me Now.
The words "lice" and "drown" are mentioned in the comments. Go figger.
