Funny mismatched Google ads

It's well known that Google has some awesomely smart folks working for them. But computers are computers and sometimes they don't get it right, in spite of the geniuses that program them. Witness this screenshot of my gmail. Google generates ad revenue by scanning your email content (yeah, a little creepy, but whatevers) and matching up advertisers to what it perceives the content of the email to be. For instance, everytime I get email from my golf club, Google will match up golf-related advertising.

This email is no exception, but click on the pic to get the full-size version at Flickr and check out the other ads that made it to the top of the sidebar. Did "cup pairings" trigger this? Go figure.
