304: Out of date advertising

The boys drink and review a chai latte stout from Schlafly, then discuss out of dates ads.  You've probably seen the headlines. The basic concept is "ads that are not acceptable today." But why are they unacceptable?  In some cases, the old ad is playful, and we're too uptight to go along with the joke.  In other cases, there were cultural assumptions in the past, or a different understanding of the science, that don't apply today. Does that make them offensive?  Some of the ads are just plain creepy, but in some cases, the very act of finding something wrong with the ad seems to implicate the critic, not the ad.  Overall, maybe we just get offended too easily these days.
