Spoofing your own ads. It's what you do.
The Martin Agency's work for Geico has often been hilariously self-aware. The whole "So easy, a caveman can do it" thing was advertising about advertising. And the "Everybody knows that" campaign figured you surely already knew the pitch verbatim.
For its latest spot, Geico goes back and spoofs itself - specifically, the famous "Hump Day" ad with Caleb the camel.
That spot was incredibly popular (it was Geico's most viral ad ever), but as you can see below, that might not be a great thing for camels generally.Source: http://www.adweek.com/
