@mm25075,
Not that I am in any way supportive of a raunchy roast like this (or Lauer) but isn't this what they do at any roast? Stretch the truth and joke about off color humor?
It is less acceptable today (and should be) but I would expect you could find many other roasts that were just as bad whether the person being "roasted" really participated in everything said about them or whether it was more an exaggeration or simple rumor.
