The first thought that came to mind was Google's "I'm feeling lucky!" button. I'm glad you mentioned it and even used it in the project!

Exactly- linking to I'm feeling lucky is the 80/20 of it. We use DuckDuckGo's "I'm feeling Ducky" in most cases since Google usually adds a redirect interstitial page (with the exception of links to youtube).
