Biden and Obama campaigned in Ohio Sunday.

TOLEDO, Ohio (CNN) – Joe Biden says there are obvious differences between himself and fellow vice presidential candidate Sarah Palin, but they’re not just on policy. She’s good-looking.

“There’s a gigantic difference between John McCain and Barack Obama and between me and I suspect my vice presidential opponent,” Biden said at an outdoor rally Sunday, getting ready to hit the GOP ticket for their economic policies.

“She’s good-looking,” he quipped.

“You are gorgeous!” a female supporter in the audience shouted out. Biden asked her to repeat it into the microphone so his wife at home would hear.

“I haven’t heard that in a long, long, long time,” Biden said as the audience laughed. “Being around this lean young-looking guy is making me feel pretty old, you know what I mean? I thought I was in pretty good shape until I hung out with this guy.”

At the rooftop rally, both Biden and Obama commented on Palin for the first time without prompting from reporters. Obama joked he’s now considering going to Palin’s home state of Alaska – the only state he says he hasn’t visited – but chose to focus his comments on her position on equal pay for women.

“John McCain’s new VP nominee seems like a very engaging person, a nice person. But I’ve got to say, she’s opposed - like John McCain is - to equal pay for equal work. That doesn’t make much sense to me.”

Palin spokeswoman Maria Comella called Obama’s comments a disgrace and “an absurd accusation.”

Obama later made sure his running mate realizes he’s good-looking as well.

“You see, she thinks you’re gorgeous too Joe,” said Obama. “Jill goes back home and look what happens!”

“This is worth the run,” responded Biden.
