Gentleman. That was no Jack Kennedy moment.
Debate watchers of a certain age can recite the line by heart: "Senator, I served with Jack Kennedy. I knew Jack Kennedy... Senator, you're no Jack Kennedy."
Sen. Lloyd Bentsen's takedown of Dan Quayle in the 1988 vice president match-up was one of the great debate zingers of all time.
So give Joe Biden credit for trying -- and Paul Ryan chutzpah points for bringing JFK up in the first place.
Ryan invoked Kennedy as he endeavored to prove that it is possible to maintain popular middle-class tax deductions and keep a broad tax cut revenue neutral. Biden's response: "Now you're Jack Kennedy?"
Nice try, Joe. But unlike that great Bentsen line, this one missed.
It was very forgettable.
