The greatest Presidency, ever

From a Politico story about the full transcript of a recent WSJ interview with Trump, comes this snippet:

At one point, Trump seemed annoyed that one of The Wall Street Journal reporters in the room called the reaction to his July 24 Boy Scouts speech “mixed.”

“There was no mix there. That was a standing ovation from the time I walked out to the time I left, and for five minutes after I had already gone. There was no mix,” Trump said.

He added: “And I got a call from the head of the Boy Scouts saying it was the greatest speech that was ever made to them, and they were very thankful. So there was — there was no mix.”

The chief of the Boy Scouts subsequently apologized for the political nature of the speech.

At what point does chronic, pathological, ridiculous exaggeration become a sign of a serious disorder rendering someone unsafe for high office?   Because he's been doing this since day one ("biggest inauguration crowd, ever") and there is no sign it is letting up and that reality is sinking in.

Update:  I see someone on Twitter is saying that the Boy Scouts are saying no such phone call was even made.(! if true.)
