I looked it up after seeing that secret. And honestly? I totally, truly don't care. It doesn't change what he does on the show or make the show any less fun or entertaining. Regardless of his resume, he does good work. It's a shame he exaggerated things, but that doesn't negate his career or abilities. I would be upset if they lied about the actual "missions" (ie, he had more help or time than actually stated), but this? Not so much. But that's just me. Besides, the overall tone of the show has this kind of larger than life bombasticness, so it actually doesn't suprise me that some of the "backstory" is fluffed up.
