You are allowed to place the label 'Sponsors' above the adverts as policy states. That is as far as I would recommend you go though. I wouldn't actual make any references on your site in any other context about AdSense being sponsors for your site as it entices people to click out of their good nature.. and that isn't good at all!

Try to enclose the area surrounding the Google ads with a table that says at the top -- Click here to win $100 or maybe just see what happens I think that will help, and hopefully it won't be too misleading for your readers. Eric
Eric, i hope you are not serious posting that. Please bear in mind that newbies who read this may take your words as truth.
