Mitt Romney talked to CNN about weighty subjects such as his standing in Ohio polls and preventing Iran from getting nuclear weapons. But his last words were on the topic of the day: the NFL replacement referees.

"I'd sure like to see some experienced referees ... come back out of the NFL playing fields," Romney said.

In case you missed it: The NFL has admitted that an error was made on a call in the Monday night game between the Seattle Seahawks and the Green Pay Packers. But the pro football league is letting the disputed call stand and affirmed the Seahawks' 14-12 victory over the Packers.

President Obama said the NFL's labor dispute with the referees needs to be settled. GOP vice presidential nominee Paul Ryan took it a step further, saying it's time to get "real refs" and equating the replacement's actions to Obama on the economy.

Asked about his running mate's take on the issue, Romney let out a hearty laugh and noted that Ryan -- a Wisconsin congressman -- is a huge Packers fan. "Paul was very angry that the Green Bay Packers, he believes, won and the referees took it away from them."

ESPN reports Lance Easley, the replacement ref who made the disputed call on the Seahawks' touchdown pass, has had four years of officiating experience and none above the Division III college level.
