text: It doesn't look like Conan O'Brien will be taking a paternity test any time soon.
  
  A 20-year-old New Jersey man named Greg Keating, who is a dead ringer for the comedian, makes the case that he's O'Brien's long-lost illegitimate son. In a YouTube video he posted on Jan. 8, Keating explains that his mother worked at NBC just a few floors away from O'Brien, and was mysteriously fired when she became pregnant in 1993.
  
  While the video is humorous, it's not clear if Keating is seriously accusing O'Brien of being his biological father. Regardless, the comedian isn't taking any chances. O'Brien has already brushed off the paternity claim in the best (and most topical) way:
  
  A kid in New Jersey is falsely claiming to be my illegitimate son. For the record, I have three children: Neve, Beckett, and @RonanFarrow. — Conan O'Brien (@ConanOBrien) January 14, 2014
