This post has been updated with a couple more examples that have come to our attention.
"I understand the tax laws better than almost anyone, which is why I'm the one who can truly fix them," Donald Trump claimed Monday in Colorado.
It is one of many issues on which Trump is one of the world's foremost experts, according to Trump. In fact, you might say he's the best at being a self-proclaimed expert.
Below is a list of the many things about which Trump says he knows more than just about anybody. Even for a guy who's fond of hyperbole, it's a lot to take in.
"I know more about renewables than any human being on Earth." — April 2016
2) Social media
"I understand social media. I understand the power of Twitter. I understand the power of Facebook maybe better than almost anybody, based on my results, right?" — November 2015
"Nobody knows more about debt. I'm like the king. I love debt." — May 2016
4) Taxes, again
"I think nobody knows more about taxes than I do, maybe in the history of the world. Nobody knows more about taxes." — May 2016
I know our complex tax laws better than anyone who has ever run for president and am the only one who can fix them. #failing@nytimes

"I understand money better than anybody. I understand it far better than Hillary, and I'm way up on the economy when it comes to questions on the economy." — June 2016
8) The U.S. system of government
"I think nobody knows the system better than I do." — August 2016
"I am a person that used to be establishment when I'd give them hundreds of thousands of dollars. But when I decided to run, I became very anti-establishment, because I understand the system than anybody else." — July 2016

"Nobody knows politicians better than Donald Trump." — February 2016 rally
11) Sen. Cory Booker
If Cory Booker is the future of the Democratic Party, they have no future! I know more about Cory than he knows about himself.
— Donald J. Trump (@realDonaldTrump) July 26, 2016
(We're putting this on the list assuming that nobody ELSE knows more about Booker than Booker, which would make Trump the world's foremost non-Cory Booker expert on Cory Booker.)
"Nobody knows more about trade than me." — March 2016

17) Defense — and offense
"So a general gets on, sent obviously by Obama, and he said, 'Mr. Trump doesn't understand. He knows nothing about defense.' I know more about offense and defense than they will ever understand, believe me. Believe me. Than they will ever understand. Than they will ever understand." — July 2016
18) The 'horror of nuclear'
"There is nobody who understands the horror of nuclear more than me." -- June 2016
