GOP vice-presidential candidate Paul Ryan said Sunday he's not counting on gaffes from Vice President Joe Biden when they debate on Oct. 11.

"I don't think he will. You know he doesn't do that in debates. The gaffes -- he's kind of legendary for this -- that's not in these kind of situations," Ryan said on "Fox News Sunday." "He's a very disciplined person when he speaks in these kinds of situations. He doesn't produce gaffes in these moments. Those are when he's off the cuff."

As for his own debate preparation, Ryan said he's not worrying about coming up with creative lines -- he's just going to be himself.

"I'm not really a line guy. I'm more of a gut guy," Ryan said. "I believe in what I believe. I do what I do. And I really believe in the policies we're providing, that we're pursuing. And at the end of the day, I'm just going to go in there and be me."

Ryan has been preparing with former Solicitor General Ted Olson, who is playing the part of Biden in mock debates.

Ryan said Biden has excellent debate skills, so his plan is not to try to rattle Biden, but to simply lay out the Romney-Ryan vision for America.

"What I hope to achieve is to give people an alternative -- a very different governing philosophy, different policies. And Joe is very good on the attack. Joe is very good at trying to confuse the issues so that the person leaves the debate confused about who stands for what. My job is to make sure that they're not confused about what we stand for and what they stand for," said Ryan.

The vice-presidential debate will be held at Centre College in Danville, Kentucky.
