A DigitalPoint Forums thread posted a screen shot of an unusual Google AdSense ad. Here is a picture of the ad:
Matt Cutts is the head of Google's web spam team. I am not sure how many sales this type of banner would lead to, since those who are looking for SEO services, may not know Matt. But it might lead to conversion for those prospects that do their homework.
In any event, this was a funny thread to spot.
