Strange people out there

I like to check my referers sometimes to see where visitors to my page are coming from. Many of them are from Google, some of which are the results of some pretty strange searches. Things like "girls in diapers" or "mango boy" I might be able to understand, but today someone stumbled onto my site looking for "John Ralston Saul on Gwynne Dyer". Ugh! I can't bear thinking about it, and can't even image looking at pictures of it...
