Cavemen
Joel, his cynical best friend, Nick, and easy-going little brother, Jamie, are contemporary cavemen who live in the suburban south and simply want to be treated like ordinary thirty-something guys. Despite their attempts at assimilation, Nick doesn't believe mainstream society will ever completely accept them, Jamie seems to take it all in stride and Joel straddles the middle, torn between his friends, his more traditional values and his loving fiancée.

*Cavemen* is a perfect example of a joke being stretched far beyond its breaking point. The GEICO cavemen worked because the commercials were short. Turning that concept into an entire sitcom only demonstrated how little material there actually was.
The characters are irritating, the jokes rarely land, and the attempts at social commentary are about as subtle as you would expect from a sitcom based on an insurance commercial. Even a talented cast, including an early Nick Kroll, can't do much with the material they're given.
There are occasional moments that almost work, but mostly *Cavemen* feels like a bizarre artifact from 2007 that should have remained a series of 30-second commercials.
It might be worth watching an episode simply to experience one of television's strangest creative decisions. Beyond that, extinction was probably inevitable.
