In 1965 or so, Campbell Mithun in Minneapolis created while MPO Productions produced this little clip, mocking the Cliché family. It's called "The Cliche Family in Television Land" and was screened at an awards show, though I am unsure which one. In it we find all the usual cliché members of the standard advertising family and learn that creatives mocked their own job as much back then as they do now. :)
Buzztown have already pounced on the material and made their own little commercial using the footage and new VO, that kills the funny.
