As the designated White House in-house humorist

"...then-Senator Kennedy was already leading the pack for the Democratic presidential nomination, but many in Washington still dismissed him as the brash son of a wealthy and unscrupulous man, a father too eager to bankroll his son's upcoming bid for the White House. Speaking at the Capitol Hilton before an audience of such skeptics, Kennedy held up what he said was a telegram from his "generous daddy" and read it aloud: "Jack, Don't spend one dime more than is necessary. I'll be damned if I am going to pay for a landslide." With a wink and a smile, John Kennedy had the audacity to tell a joke that, out of the mouth of another, would have been nothing less than devastating. This was my idea of a profile in courage.

[from Newsweek:........]

Most jokes that politicians tell don't make you laugh because they're too carefully calculated to be funny. Mitt Romney tells one that's carefully calculated and funny. "I believe marriage should be between a man and a woman," he recently told an audience of conservative Republicans. "And a woman, and a woman and a woman."

The Problem with the World
One of Lincoln’s neighbors told how he went to his door one day to determine why some children in the street were shouting. He saw Lincoln walking past with two young boys in tow. "What’s the matter, Mr. Lincoln?” the neighbor asked. "The same thing that’s the matter with the whole world," Lincoln answered. "I have three walnuts, and each one of them wants two of them."
