I was playing with the Adsense data today and stumbled on this little stat:

According to Adsense, someone has been targeting my link units from August 10th to November 22nd. I'm assuming it's some sort of glitch because as far as I know, advertisers can't target link units. It's possible I entered the wrong channel code in the Adsense script, but I would expect more than 15 impressions if I miscopied the Adsense code.
And take a look at this ad on my site. It's for the bird flu. What the heck is that ad doing on my site?
