All you guys with thousands of hits but no income should try offshoreclicks. They have a pay per impression program, meaning they pay you for every unique visitor that views your page. They spit out a pop up though, so if those bother you it won't work.
Try it here if you want:

They also don't require a Tax ID from US citizens, if you're worried about that sort of thing.
