How The Heck Does Google Work?

I added a web counter to this blog last week. The number of visitors goes up (ever so slowly) every day and none of the hits are mine!

What I find incredible is that:

1. The most popular word that drives Google users to my words is "Leprachorns" and
2. If you type "Leprachorns" into Google this blog is top of the list.

I can only assume that I've spelt the word wrong!
