http://www.myspacescripts.com Click on one of the generators and it launches a popup with an adsense advertisement in it. I hope Google gets this person soon.
The main page has yahoo but when you click on a "generator", it will pop up the generator page with an adsense banner. Scroll down a little until you see a list of the scripts, click on one of them and you'll see.
Hm, show the direct link and tell where we must click to see this. I can't find this. BTW, I saw later also google ads, but not in pup-up. /
