You Can Stick Google AdSense… 1
I’m not telling you where to stick it and it’s not even my idea - AdSense folks have come up with it themselves - go have a look to get the complete story. Pay the shipping and handling and stick it all you want 
Among other news, AdSense is experimenting with ads - I have noticed recently these arrows next to the AdSense ads on one of my sites that still has them:
Other people have been reporting seeing these arrows since December 2007 and I have found explanations in Google AdSense forums that this was an experiment - well considering that there’s still no official word on it anywhere in AdSense it probably still is an experiment.
