It turns out that Thamsanqa Jantjie is more than just a fake signer who punked the entire world, standing next to American president who has also punked the entire world. He was having a schizophrenic episode right there on stage at the Mandela funeral.

Jimmy Kimmel had some fun with the whole bizarre episode. Last night he brought an actual sign language expert onto his show to translate Mr. Jantjie’s work.

Or, punk the country one more time. Either way, it’s hilarious.

CNN took Mr. Jantjie’s fraud a little more seriously. Anchor Chris Cuomo brought on an expert to tell the audience how to spot a fake sign language interpreter. That information would have been a bit more useful to the committee who arranged Mandela’s funeral, before the fraud actually stood on stage.
