Born March 15, 1767, the 7th president was 69 years and 354 days when he completed his second term in March 1837. Though “Old Hickory” had a reputation for being a rugged ex-soldier and outdoorsman, by the time he reached the White House, he already had spent years coping with a variety of ailments.

According to biographer H.W. Brands, samples of his hair reveal that he had lead poisoning from old bullet wounds. Jackson also struggled with chronic diarrhea from diseases he’d contracted while fighting the Indians in the 1810s. His habits of smoking and chewing tobacco didn’t help his health either, and according to biographer Sean Wilentz, Jackson became so sick at times during his two terms that it appeared he might not survive.

Jackson did make it to the end of his term but when returned to the Hermitage, his plantation in Tennessee, the white-haired ex-president was physically spent and suffered from blinding headaches, insomnia, severe pains in his side and a chronic cough.

Abraham Lincoln on Stephen Douglas’ policy on slavery: It 'is as thin as the homeopathic soup that was made by boiling the shadow of a pigeon that had been starved to death.'

Lincoln, who used that tortured metaphor during his famous 1858 debates against Stephen A. Douglas for Senate, is known for his eloquence, less so for his ability to craft brutal one-liners.

Lincoln didn’t win that race, but the publicity he gained during the campaign helped him secure the presidency just a couple years later.

Theodore Roosevelt on William McKinley : 'McKinley had no more backbone than a chocolate eclair.'

If it wasn’t obvious, Roosevelt perceived McKinley as a flip-flopper. Awkwardly, Roosevelt became that McKinley’s vice president two years later. And just a few months later, Roosevelt succeeded to the presidency after the man he’d once compared to a French dessert was assassinated.

Teddy’s experience as president didn’t stop him from trashing other ones, either. Using terms that are essentially meaningless today, he called President Woodrow Wilson “a Byzantine logothete backed by flubdubs and mollycoddles.”

President Harry S. Truman on General Dwight D. Eisenhower: 'The General doesn’t know any more about politics than a pig knows about Sunday.'

Truman had those choice words for Eisenhower as the general ran for the Republican presidential ticket in 1952. Eight years later, when Eisenhower’s vice president Richard Nixon decided to run for president, Truman denounced Nixon as “a no-good lying bastard,” and told a crowd that anyone who votes for him “ought to go to hell.”

Years later, Nixon’s vice president Gerald Ford would offer his own quip about Nixon and hell (read on).

Dwight D. Eisenhower on Richard Nixon contributions as his vice president: 'If you give me a week, I might think of one. I don’t remember.'

Before Richard Nixon was our infamous 37th president, he was Dwight D. Eisenhower’s veep. Judging by the remark Eisenhower made at a 1960 presidential news conference, they didn’t get along so well.

Time correspondent Charles H. Mohr was asking Dwight about what Nixon actually did in his administration, and was getting some pushback. Dwight said Nixon “was not a part of decision-making,” and Mohr countered that he must be doing something.

“We understand that the power of decision is entirely yours, Mr. President,” he said. “I just wondered if you could give us an example of a major idea of his that you had adopted in that role, as the decider and final—”

That was when Dwight cut him off, saying he’d need those seven days to think of one.

Lyndon B. Johnson on Gerald Ford: 'Jerry Ford is so dumb that he can’t fart and chew gum at the same time.'

LBJ was one of the crudest presidents in U.S. history. In one instance, when reporters asked him why the United States was still in Vietnam, he pulled out his penis and answered, “This is why!” Another time, he let a reporter know he didn’t like his recent article by, as the New York Times puts it, “defecating on the ground in front of him.”

Given this, it’s not terribly surprising that his burns were often scatalogical.

He was also preoccupied with people knowing in what department he was superior to John F. Kennedy, the president he’d served under and succeeded. “When people mentioned Kennedy’s many affairs, Johnson would bang the table and declare that he had more women by accident than Kennedy ever had on purpose,” writes presidential historian Robert Dallek in The Atlantic.

Gerald Ford on his own, unpopular pardon: 'I know I will go to hell, because I pardoned Richard Nixon.'

Like Johnson, Gerald Ford was a vice president who succeeded to commander-in-chief. But unlike Johnson, he didn’t fill the role because the president was dead—he did it because the president had resigned.

Richard Nixon’s resignation over the Watergate scandal was already shocking enough. But then Ford went and pardoned Nixon, preventing him from facing any legal consequences for his actions.

It was an extremely unpopular move, and Ford knew it. In private, he reportedly confessed his regret to confidants.
