"Oh God, it's Mom": Pundits surprised on live TV by call from mother

Political commentators of all stripes know that their outspokenness and opinions will leave themselves open to constant criticism. But they might not expect it would come so publicly from their own mother.

Brothers Brad and Dallas Woodhouse appeared on C-SPAN Tuesday to discuss their upcoming documentary about bipartisanship and the political divide splitting the country. Brad is liberal and Dallas is conservative.

The two were debating the merits of Obamacare when the host took a call from a woman named Joyce in Raleigh, North Carolina -- Joyce being Joyce Woodhouse, Dallas and Brad's mother.

Right after he recognized his mother's voice, Dallas covered his face and said "Oh God, it's Mom."

C-SPAN host Steven Scully noted that the call was completely unplanned.

Joyce described her love of politics, but was critical of her sons' penchant for bickering during the holidays. Brad and Dallas spent Thanksgiving apart this year, so Joyce made it clear she expected their C-SPAN appearance to get all of the arguing over with, at least for now.

"I'm hoping you'll have this out of your system when you come here for Christmas," she said.

CBS News reached out to Joyce, who said Brad called her to make sure she was not really angry. She assured him that she just wants everyone to get along this holiday season.

"I really would like a peaceful Christmas," she said on C-SPAN.
