Curious. I haven't been in chat in forever, so I wouldn't know about Mibbit banners, but I've never seen said ad on FBTB. I'm getting a lot of Allstate and Party America ads though.
Actually, I wonder if we could take this thread into the direction of bizarre banners members see on this site. I feel like that could get really interesting.
I am the brain, that which keeps you sane
I think your thoughts, I feel your pain
I am able to control both body and soul
I am never asleep, and I make you whole.
