Barack Obama has a strategy to discourage his daughters from rebelling - perhaps by getting a tattoo himself.
The US President said he and his wife, Michelle, have told 14-year-old Malia and 11-year-old Sasha that if they ever decide to get a tattoo then "mommy and me" will get the same tattoo in the same place on their bodies and show it off on YouTube as a "family tattoo".
Mr Obama made the comments in an interview taped last week and broadcast on NBC's Today.
The President also dismissed the First Lady's recent reference to herself as a single mother during a separate television interview.
He suggested the comment was a slip of the tongue. But he also acknowledged there have been times in his political career when she probably did feel like a single parent.
