According to a report in Cinema Blend, holy f@ck, Andy Kaufman could be alive or maybe he's still pranking us after all these years:
The story begins at the 9th annual Andy Kaufman Awards, which were held on Monday night at New York's Gotham Comedy Club. While on stage, Michael Kaufman - Andy's brother - began to talk about his sibling's legacy and then revealed that he doesn't actually know if Andy is alive or dead. He then told a story about how back in 1984 he was going through his brother's things and discovered an essay written by Andy about how he would go about faking his own death. The piece said that he would eventually reappear on Christmas Eve 1999 at a particular restaurant, and when that date came Michael went to the place to find out the truth. While Andy was a no-show, that night he was given a letter from a stranger that turned out to be a letter addressed to him from Andy. In the letter the comedy legend explained how he wanted to have a normal life and that "he'd met and fallen in love with a woman and had a daughter, and that he didn't want Michael or anyone to say anything while their own father was still alive."
Andy and Michael's father, Stanley, died this past summer, and Michael told the audience at the Gotham Comedy Club that a month after the loss he got a call from a young woman who told him over the phone that Andy was alive and that he had actually been paying attention to the Andy Kaufman Awards "from afar" and was very proud of the event. Michael then asked the crowd if that young woman was in the audience, and then a 24-year-old woman stood up from the back and made her way to the stage. The report on The Comic's Comic, which was written by a writer named Sean L. McCarthy, doesn't mention exactly how this young woman was connected to Andy, but Killy Dwyer, an Andy Kaufman Awards finalist who was there that night, said in a Facebook post that the mystery guest was Andy Kaufman's daughter.
