If you go on to Google and type in "who's the cutest" and click "I'm Feeling Lucky" it will say "YOU ARE" in big bold letters. Go try it out! "I'm feeling lucky" takes you to the first result in your google search.
So instead of seeing a list of search results to choose from, you go straight to the first result. www.whosthecutest.com is the first result for "who's the cutest", so that's where you go when you click the "lucky" button. It's just a grey page with the words "YOU ARE" in big letters.
