Volkswagen brings Fail to a whole new level

Ok, forget the disgusting antics of these women attempting to pick up a guy half their age in a Volkswagen dealership by bleating lame innuendo that, if uttered by a guy at a bar, would get a drink thrown into his face. Once again I could point out that if you reverse the roles here and feature three old men tossing sleazy lines at a young female seller this ad probably gets rejected during production and never sees the light of day.  Because, you know, it's 2015.

Because the lines are being put into the mouths of elderly women, and are being directed at a guy who works at the dealership, it's not only stupid, but also very confusing- aren't these women customers?  Then why are they trying to sell the car instead of letting the salesman do that?

I could do an entire second post on all this, but I'm not going to bother.  I'm way too interested in getting an answer to just one question:

Why are elderly women, children, and animals ever used to sell anything that is not specifically geared to elderly women, children, or animals?  I just don't get it, and I never have.
