Going From Zero to Indexed On Google

I did this experiment the other day to figure out how long it would take for a site to get indexed on Google. I basically went to 1&1.com and registered a brand new domain. Then I put a blog on it, and wrote an article about Amazon Kindle. Then I submitted it to Digg. Once it got a few votes, I was sure that I would be indexed rather quickly, but how quickly you might ask: 2 days. Actually the whole process took two days, from domain registration to getting indexed on Google. I wonder if anyone has managed this in a shorter period of time. What does the guinness book of records say?
