Cavemen! I loved the insurance commercials, and was surprised and delighted when I heard they had actually decided to make it a sitcom, since so many people had loved the commercials right along with me.
And it is about as classic a sitcom as one could hope for, true enough to the genre to literally become a textbook example of one.
It would be unrealistic to expect it to be as good as the commercials, though, and it is not.
Still, Mr Puff and I laughed at it. But then we are just a couple of sapes.
