Why is there an "I'm a Mormon video ad" on my blog?

I keep waiting for that check from Google for letting them post their ads in my personal space and it's like waiting for the tooth fairy. If ye shall perchance stumble upon this trusty forsaken blog kindly do the following: click on the ads before you read my posts. In fact, I forbid ANYONE to read my highly entertaining posts unless they have clicked on whatever Google deemed suitable to place on the right and bottom of the screen.
P.S. I did not make up the title. There really is an "I'm a Mormon" ad on my blog. Who can I inform that "I'm a Jew?"
