MSNBC host Lawrence O'Donnell has accused President Ronald Reagan of telling a gay sex joke 32 years before Lena Dunham's “first time” ad.

Responding to backlash from conservatives to Dunham's suggestive ad for the Obama campaign, O'Donnell called Dunham's spot “the hippest ad in presidential campaigning.”

“The can't-take-a-joke crowd is, of course, outraged,” O'Donnell said, a reference to ad's sexual subtext.

(Related: Lena Dunham's first time was with a candidate who supports gay marriage.)

That crowd, O'Donnell added, thinks Reagan – a Democrat turned Republican – is a candidate for sainthood.

“[W]hen he was running for president, Ronald Reagan told a double-entendre joke that ingeniously included, within its overall double-entendre structure, an internal double-entendre that allows for both straight and gay entendres,” O'Donnell said before playing a clip of Reagan telling his gay-straight joke.

“Listen, I know what it's like to pull the Republican lever for the first time, because I used to be a Democrat myself. And I can tell you, it only hurts for a minute, and then you'll feel just great.”

Oh, my,” O'Donnell quipped. “Now, I don't think we have to decide whether Ronald Reagan intended that to be a straight or gay entendre. The guy was a Hollywood actor. He had seen it all. And he knew, there is never, never a joke that has too many entendres.”
