I sort of took Johnny Carson for granted when I was a kid. Yes, I'm old enough to remember Jack Paar but I was young enough when Carson took over not to realize what had happened, or even that it was the same show. In fact, once Carson took over, it really wasn't the same show, was it? Nothing against Leno (and I am trying to keep myself from thinking baaaad thoughts about O'Brien's taking it over; maybe he'll be a TAD less silly? I know he CAN be less silly. 9/11/2001 he was less silly...) but Carson really made it his own. Even with guest hosts, I don't think anyone actually ever imagined he would ever leave (I mean the show).
