Honestly, if an advertisement looks interesting, I'll click on it. I know, I'm just provoking them. :P
But I still said 'no' because it's really rare that there is an ad that is actually interesting. Being the complete pokenut that I am, I clicked on the "Free Online Pokemon MMORPG!" thing the first time I saw it, but then I quickly learned it was just a rip off of some other game and that you could get viruses/spyware from downloading it.
