I'm with G Gordon on about 85%...he's more of a social/cultural progressive than I. My wife does think he's cute for an elderly fellow. If he is virile and potent and all that I wonder about his new girl Friday Diana....they seem mighty chummy.....and he admits to a rather open marriage. Of course it might be shtick like you said.
He's such a mouse on P.I. that I have a hard time believing in his radio machismo.
