Presidential humor is only a half-step from dad humor, which in the world of comedy is considered light treason But we've tried to find at least one joke from every U.S. president, to mark President Obama's final set of stand-up comedy at his eighth White House Correspondents' Association dinner on Saturday.
Some are flat, some are apocryphal, some are just threats and some, in the case of Warren Harding, are quaint loving references to the chief executive genitalia. But they are presidential, by definition, and therefore funny, by acclamation.
Here is a list of the funniest ones!
Barack Obama, at the 2012 White House Correspondents' dinner
"I have a lot more material prepared, but I have to get the Secret Service home in time for their new curfew."
George H.W. Bush, at the 1989 Gridiron Club dinner.
"People say I'm indecisive, but I don't know about that."
Ronald Reagan, to protesters at UCLA
"'Make love, not war'? By the looks of you, you don't look like you could do much of either."
Lyndon Johnson, on Ford
"So, dumb he can't fart and chew gum at the same time."
"John Calhoun, if you secede from my nation I will secede your head from the rest of your body."
John Quincy Adams, on Jackson
"A barbarian who cannot write a sentence of grammar and can hardly spell his own name."
James Monroe, to Alexander Hamilton
"You are a scoundrel."
Thomas Jefferson, on John Adams
"He is as disinterested as the being who made him."
John Adams, on Alexander Hamilton
"That bastard brat of a Scottish peddler!"
George Washington, in a 1788 letter congratulating the Marquis de Chastellux on his recent marriage
"Now you are well served for coming to fight in favour of the American Rebels, all the way across the Atlantic Ocean, by catching that terrible Contagion - domestic felicity - which like the small pox or the plague, a man can have only once in his life: because it commonly lasts him (at least with us in America - I don't know how you manage these matters in France) for his whole life time."
