Boss Romneybot owns his humorous birther routine in an interview with CBS Evening News host Scott Pelley:



MITT ROMNEY: Well, we're in Michigan, and uh, both Ann and I were born in Detroit. And of course a little humor always goes a long way, so, uh, uh, it was great to be home. To be in a place where Ann and I had grown up, and uh, the crowd loved it and got a good laugh.

PELLEY: But this was a swipe at the president and I wonder why you took it.

ROMNEY: No, no. Not a swipe. I've said throughout the campaign and before there's no question about where he was born. He was born in the U.S. This was fun about us and coming home. And humor, you know, we've got to have a little humor in a campaign as well.
