Today was the first day I spotted a Google AdSense Flash ad on Cartoon Barry. I noticed a little X box at the top right, when I moused over it, it said "close". So I decided to document the whole process.

Clicking Close Actually Made the Ad Disappear:

It came back after I refreshed a few times, but I honestly thought it wouldn't close out the ad, I thought it would take me to the AdSense Feedback Form, I guess I was wrong.
