They dont pay out on just impressions right? This is weird but lately I have been getting a penny to 4 pennies and no clicks. Today I had 91 impressions and got a penny. NO CLICKS. Is that really possible? I mean I look at it like this.. If I get 4 checks a year from them that almost offsets my domains and hosting so Im happy.

Yes, they do, check out your advanced reporting to see how much is via placement ads. Looks like most is, though.
Some ads pay CPM, but unless you have a LOT of traffic, it won't really add up to much. Keep in mind that CPM is per thousand impressions, but these reports are "estimates" so you can get $0.01 when you have less than 1,000 impressions based on it estimating when/how you will get 1,000.
