He seems to just spin tall tales out of thin air.
This is him telling a story from the very first Royal Rumble. Cliffs: he says he's the one who wrote that whole match, but that he screwed up and forgot to write where Rick Martel should be eliminated. Suddenly in the middle of the match they realized that Martel was just still out there and that they hadn't accounted for when he was supposed to go away. Pat Patterson was flipping out and saying, "What the hell is Martel still doing in there??" Realizing the issue, they told the next person to go out and eliminate him.
Slight problem: Martel was not in the first Royal Rumble. He was in the next two, but neither one seems to have facts that can align with this story. The '91 Rumble at least has facts that can square with Martel hanging around longer than he was meant to, though it doesn't square with one of the late arrivers going in and knocking him out; he was eliminated by Bulldog, and Bulldog was in for an eternity before eliminating him.
There might have been kernels of truth in the Martel story, but I just don't find him trustworthy. (I do not buy that Hulk Hogan was originally to take on "Sheik Tugboat" at WrestleMania VII in the main event.)
