Remember Thamsanqa Jantjie, the "fake" sign language interpreter at Nelson Mandela's funeral who later admitted he was making it up?
Not only did he not know any sign language, it turned out he had been diagnosed with schizophrenia and had a violent past.
And now a technology start-up has put him in their latest advert.
The company says it got a Zulu-speaking journalist to visit the hospital and get Jantjie out for the day, on the premise of a "family visit".
This case raises huge ethical questions, mainly around whether Jantjie was exploited.
Here's the full advert.
UPDATE 16:00 BST: The company's CEO, Max Bluvband, says the company had no intention to exploit Jantjie.
The entrepreneur told BuzzFeed this afternoon that Jintjie was able to leave hospital and take part in the video of his own free will and with permission.
"I think we did a very good thing – we didn't take advantage of him," he says. "We approached him in a very normal and regular way. Now he is getting back on his feet."
He added that if the company had known the stunt might have offended people, they wouldn't have done it.
