Two key players in Donald Trump's campaign have revealed what the President is really like behind closed doors in a revealing new book.
In Let Trump Be Trump, released overnight in the US, Trump's early campaign manager Corey Lewandowski and deputy campaign manager David Bossie provide an insider's account of how the real estate developer pulled off the biggest political upset in history.
The book is at pains to paint the President as a mould-breaking hero, but it unwittingly provides a steady stream of laugh-out-loud moments that often make Trump look like a petulant brat incapable of admitting his own mistakes.
It's worth noting that the book is nakedly self-serving. Lewandowski and Bossie are out to claim credit for their roles in Trump's election and, strangely, refer to themselves in the third person throughout the book, despite being billed as its sole authors.
With that in mind, here are some highlights.
Trump will 'tear the face off' staff when he's cranky
Temper, temper, Mr President.
The book's 278 pages are a parade of colourful anecdotes about Trump tearing shreds off his staff members and chucking tantrums when things don't go his way.
"Sooner or later, everybody who works for Donald Trump will see a side of him that makes you wonder why you took a job with him in the first place," the book says.
"The mode that he switches into when things aren't going his way can feel like an all-out assault; it'd break most hardened men and women into little pieces.
"Around the campaign, we call it getting your face ripped off."
In one episode described in the book, Trump turns his rage towards campaign manager Paul Manafort, who the candidate felt was trying to control him during debate prep.
"Am I a baby, Paul?" Trump thundered.
"You think you're so f***ing smart! Like you're a genius! Well, you suck on TV."
After the blast, Manafort "looked like a crushed blue beer can".
In another encounter, Trump went "f***ing ballistic" when he read a tweet that claimed Manafort wanted to limit the candidate's appearances on TV.
"Did you say I shouldn't be on TV on Sunday?" Trump screamed to Manafort down the phone while in a helicopter.
"I'll go on TV anytime I goddamn f***ing want and you won't say another f***ing word about me."
Another episode presents Trump as decidedly ungrateful to Republican Rudy Giuliani after he took a whole round of bullets for the candidate.
When the infamous "grab 'em by the pussy" tape was leaked in the final weeks of the campaign, nearly all of Trump's supporters abandoned him.
However, New York mayor Giuliani put up his hand to appear on all five Sunday morning TV shows to defend Trump.
After being bollocked by the toughest political journalists in the country — picture going five rounds with Leigh Sales — this is how Trump thanked Giuliani: "Man, Rudy, you sucked. You were weak. Low energy."
Trump also tore strips off his media adviser Hope Hicks when she once forgot the steamer used to take wrinkles out of his suit.
"Goddammit, Hope! How the hell could you forget the machine? I want it now!" Trump bellowed.
The authors say that Trump's campaign ran on junk food — and one of the greatest challenges was making sure you had it hot and ready whenever Trump happened to grow peckish.
No joke, the book says: "The orchestrating and timing of Mr Trump's meals was as important as any other aspect of his march to the presidency."
Trump hardly ever ate lunch, but dinner was usually Macca's washed down with a chocolate thickshake, which he referred to as a "malted".
And Trump's order had a hint of the Hamburglar about it.
One night in Chicago, the candidate ordered two Big Macs, two Fillet-O-Fish burgers and a chocolate "malted".
"On Trump Force One, there were four major food groups: McDonald's, Kentucky Fried Chicken, pizza and Diet Coke," the book says.
Trump, whom the authors refer to as "the boss", is also painted as a germaphobe who would only eat his beloved Oreo biscuits if the packet was unopened.
"If you've seen the Seinfeld episode in which George double-dips his chip, you have a pretty good idea of the boss' reasoning," the book says.
Another fun fact from the book: Trump loves Elton John and will blare his music "loud enough to rattle your brain".
Donald, you're a star in the face of the sky.
He is super superstitious
The book describes Trump as "one of the most superstitious men that most people have ever met".
It says he throws salt over his shoulder before meals and pre-emptively celebrating a win is seen in Team Trump as inviting "bad juju".
Lewandowski explained the "gratuitous boasting" by saying his "thoughts sometime come out like pieces of a puzzle".
"Sometimes the puzzle pieces form a masterpiece," the book suggests.
The book makes clear that Trump "never apologises" — and never feels the need to ask God for forgiveness.
The blame for mistakes is always placed at the feet of his staff.
"I'm doing a great job, but my staff sucks," Trump told Lewandowski after his inauguration.
The campaign's ignorance was a strength
Despite having the backing of a multi-millionaire, the Trump campaign started small; little more than a cubicle wedged into the 24th floor of Trump Tower in New York.
In fact, the authors view the team's political ignorance as a strength — because "they never saw us coming".
"It's remarkable when you think about it," the book says. "Donald Trump launched his presidential campaign with a tweet, an escalator ride and a staff that mostly wouldn't know the difference between a caucus and a cactus.
"There were no pollsters, media coaches or focus groups. No speechwriter, no 'senior strategist' or any of the other types of 'professional' political consultants like the ones who had failed for the last eight years to elect a Republican president.
"We were the island of misfit toys."
In the early days of the campaign, Trump spoke off-the-cuff almost exclusively, and he greatly resisted being prepped for debates with standard talking points. The voters got Trump uncut, for better or for worse.
His war on political correctness won the election
What the book gets right is its appraisal of Trump's ability to reach and inspire American voters by eschewing political correctness.
"His assault on political correctness resonated with people across the country," the book says.
"Whether it was Rosie O'Donnell's weight, or a federal judge, or any of the reporters following the campaign, no one was off-limits.
"And only Donald Trump could get away with what he got away with."
The authors say his opponents and the media were "tone deaf" to the voters' views on immigration and radical Islamic terrorism.
"They were tired of the PC doubletalk from coastal elites and even more tired of those condescending attitudes," the book says. "The boss took a flamethrower to all of it."
The authors appear completely comfortable with some of the President's most jarring comments during the campaign, such as when he referred to Mexicans sending their "rapists" across the border, and when he said senator John McCain was "not a war hero" because "he was captured".
