Obama warns daughters on 'family tattoo'
US President Barack Obama has warned his daughters that if they get tattoos, he and his wife will get matching ones on the same place on their bodies.
In an interview on NBC's Today show, Mr Obama said he hoped the "family tattoo" threat would discourage teen rebellion.
Mr Obama said he had warned Malia, 14, and Sasha, 11, that he and First Lady Michelle Obama would show off their matching tattoos on YouTube.
The girls are the first teenagers in the White House since Chelsea Clinton.
Ms Clinton was 12 when her father President Bill Clinton took office in 1993.
In the interview the president also reacted to Mrs Obama's recent remark that she was a "busy single mother".
In her own interview with a local television news station, Mrs Obama quickly corrected herself.
Calling the first lady's comment a slip of the tongue, Mr Obama added that at times - for instance when he was running for office - Mrs Obama was both working and looking after their daughters and may have felt like a single parent.
