Geico Advertising

I have to wonder about the advertising agency that Geico uses http://www.geico.com/about/commercials/.  Think of all the wonderful advertisements they have had over the past many years:  The Caveman Series, The Gecko Series, now the play one words.

The advertising has not convinced me to change insurance companies, but you after wonder what working for a company that portrays it self so less than seriously is like.
