What I heard was that a lot of things seemed incredible. As in they lacked credibility. Root canal sans anesthetic and getting on a plane wearing a shirt covered in blood, vomit, and snot, to name the two most glaring examples. Other people had questioned these (and other) 'facts' from his book and some had written SG to have them look into it. I'd say they looked into it rather deeply.

I'd also say 'What's the big deal' except for his oft proclaimed sincerity in spilling his guts and being completely transparent to the public, hiding nothing and baring all. He has purported these events to be factual occurences not only in his book but in the interviews he has done as well. The SG article certainly seems to expose several events as greatly embellished, at the least.
