Its an image rotation site w/ different categories. And considering its rather poorly designed as far as layout is concerned, I guess its not to bad of a ratio as var as visitors is concerned. http://www.miscipedia.net/rofl
You should be getting far more many clicks than you currently are. You need to blend those ad blocks into the layout. They both stick out like sore thumbs.
Why don't you try Adsense videos? That will nicely blend with pictures. Also, I most of your ads are not relevant. Use tags with pictures
