Looking at the front page of my blog, I noticed a bunch of gay (as in of interests to the lgbt community) ads. Clearly, the post about the movie plot caused this.
Google Adsense is like a trained monkey: give him a fruit bowl and he'll hand you a banana. The point wasn't that they were gay, the point was that the premise was flawed.
Maybe that's good. If Google really knew what the post was about, their search function could probably do some very creepy things.
Now what's the monkey further down the page up to, these days?
