Poll: Have you ever clicked on a Facebook ad

I don't think I have clicked on facebook ads, and neither have the friends I have polled. I am wondering what the HNs community has done?

I've never clicked on an ad other than by accident on any site. Of course I use adblock, but even if ads were to be displayed I can't imagine anyone directing any attention to them once they are recognized as ads - which would be at the first glance at the page. I am certainly never aware of what ads are for or what they say any time one slips onto my screen.
