President Obama snaps a selfie at Mandela’s memorial service

Fresh off the latest round of controversy regarding when and where it’s appropriate to take a photo of yourself, President Obama, British Prime Minister David Cameron and Danish Prime Minister Helle Thorning-Schmidt apparently snapped a selfie at Nelson Mandela’s memorial service, where they’re all guests.

The photo shows the three smiling for a smartphone while Michelle Obama stares into the distance. A series of hilarious follow-up photos, practically screaming for a caption contest, show Obama laughing with Thorning-Schmidt and touching her arm before turning inexplicably somber. The first lady looks stern -- dare we say disapproving? -- throughout.

Thorning-Schmidt and Obama have met officially at least twice before, most recently in September in Stockholm. Thorning-Schmidt also visited the White House in February, when she and Obama discussed economic policy and the situation in Syria. The Danish PM also has daughters slightly older than Malia and Sasha Obama, which came up during the meeting.

For the record, CNN last October asked Emily Post, that last bastion of old-school etiquette in this topsy-turvy Internet world, whether it was ever okay to take selfies at funerals.

“No!” replied Post -- exclamation point hers.
