Obama and Castro, the Weird Handshake

Is that a manshake gone awry?

Forget about the thought that dissidents were arrested moments before President Barack Obama landed in Cuba. The really damaging news is likely to be the hilariously awkward moment that is playing out on social media with Obama's hand and arm going limp as Cuba's Raul Castro raises it in the air.

The moment, aired live on television around the world, is now being shared and retweeted over and over again. Is this the new "mom jeans" moment for Obama?
