As if the president's selfies weren't enough, it became very apparent to those in the international sign language community that this interpreter here was basically just making things up on the fly and foregoing that whole "interpreting" (or "making sense") thing entirely.

Maybe it's just the timing of these photos and the power of photography, or maybe Michelle Obama is just really really not going to put up with the POTUS's behavior at the Nelson Mandela memorial service. Speaking of which, there's a narrative you can probably craft based on these photos here:

Likely that narrative is "Barack Obama got up to pee and Michelle stole his spot" but the alternative is just a bit more entertaining.
