Viewing directions: 1. Look at the screenshotted article headline. 2. Look at the ad up top.
There are actually two pretty good explanations for this - check them out after the jump. The DP uses Google Ads for most of their site, so they didn't buy the ad running at the top of the page. Google usually scans the content of a page or a site before displaying an ad, so this hilarious juxtaposition could have more to do with the content of the page than anything else. The other possibility is that the tipster who screenshotted this pairing visited the advertised page at some point in the past and Google just held on to that information - in which case we've got a trigger-happy tipster on our hands.
