Last week, a guy named Greg Keating went on YouTube claiming to be Conan O'Brien's illegitimate son. While he does look a bit like Conan, it's not entirely clear if the video was meant to be a joke or not. Either way, Conan took to Twitter today to set those rumors to bed. Ronan Farrow will probably be relieved to know once and for all that Woody Allen is not his father.
