I actually remember watching an old Howard Stern vid on youtube a long time ago that had Rogan on as a guest. Howard was interviewing Rogan, the half sister called in (who I assume is the same woman in the vid) and asked Rogan to meet with his Dad, Rogan wanted nothing to do with his biological father and declined the offer. This interview must have taken place in the late 90's or early 00's I'm sure.
