Well, from the website, CSI got 18.2, followed by Desperate Housewives with at 15.8.
But I do remember seeing Friends getting post 20 numbers... but it's so long now, and I have no idea where to find old Friends numbers.
But yeah, there are more Spongebob fans than... well, SciFi fans? That's kind of scary.
Those kids are going to take over the world!
