MajesticSEO just recently released a list of Google's strongest backlinks:
Google’s Strongest Current Backlinks | Majestic SEO Blog

You can actually download the entire list of all of Google's best links.

I started looking through the list, and there are definitely a bunch of sites there that I haven't heard of. Maybe I'll be able to get a few links on some of these sites?

Here's the top 20 (there are 30,000 more):
