Google Searches

A lot of the hits on this blog come from Google. I get to see the last 20, though I only know the time and query and nothing else (check it out here). This evening I just thought I'd check it out, and I saw the following search string that made me laugh:

calculate the value of π using the Monte Carlo method using a quarter-circle in programming C

I'm guessing that the person searching must have already read the post once before, and wanted to come back. That's the first time I've seen someone type the letter π into Google though!
