Indeed. I was reading through those and wondering when they would get to “The way these politicans are going we’re going to have a Presidential Sex Scandal soon!” or “Next thing you know we’ll be listening to music that glorifies gansters!”

From 1963; Kennedy to Johnson: "You need to be President like I need a hole in my head."
From 1971: "Man, I'd die to get it on with Claudine Longet."
