icymi: that is Rob Reiner playing "Moondog" ... it's the episode where they help Gomer camouflage a Marine vehicle but paint flowers on it, instead.
Good grief! What did they do to that poor chick's face? Typical "TV hippies" back then. Caricatures. Loved watching it, though. Rob Reiner with the Sonny Bono hairdo! Gomer with his surprisingly good voice. Crazy.
