I'd rather them make a TV show out of the cavemen than the gecko because....I like my gecko in small doses. If they made an entire TV show out of the gecko, they'd be over-doing it, and the gecko would be less funny, thus ruining the gecko. By the way, what's the gecko's name anyway? And speaking of geckos, does anyone remember the video game Gex: Enter the Gecko?
Back to the cavemen. You don't quite love them as much as the gecko, and therefore won't be sad when the ratings plummet into oblivion. The cavemen show is like an experimental show before they turn the gecko into a show, except they're never going to turn the gecko into a show. So they're just risking their slightly less funny thing.
