I saw it via FastClick in a leaderboard (728 wide) ad unit. Interestingly, the "Ads by Google" was not a link. The colors/style seem to be a standard default, because it was not the same ad colors and styles that were used on the same page when targeted ads appeared.
I can only imagine what some companies would be willing to pay to see their entire ad in large font across a single leaderboard unit. It was quite noticeable and jumped right out at me, even though it was a single color with a white background.
Guys: set up your own alternate ads. You can even set a charity if you want. There are a bunch who accept online donations and have some nice media that you can use to link. I know... I link to one from my homepage </hint>
