The literature depicted below may have broken certain societal taboos (pot is good, sex is fun, authority is a real drag, man), or it may have been utterly without socially redeeming value but, for a certain portion of the young and (I'm guessing), mostly male population, this was the first comical view into the truly illicit goings on of the hippie culture and oh, man, was it ever groovy. Keep on Truckin' indeed; just don't admit it to your children!
When your first waking thought tickles the comedy in your soul, there's a pretty good bet it's going to be a real good day. HL 2009
