Roseanne Barr Tells Obama To Leave Her Weed Alone On 'Late Show With David Letterman' (VIDEO)

Roseanne Barr told David Letterman on "Late Show" (weeknights, 11:35 p.m. ET on CBS) that she agreed to be roasted on Comedy Central because the network said they wanted their next celebrity target to provide a "classy" roast. And that was just the tip of the iceberg, as the opinionated comedienne was all over the place during her appearance.

She ranted about medical marijuana, railing against the president. "Obama, you’ll get my joint when you pry it out of my cold, dead fingers."

She even managed to associate proposed legislation that would force porn stars to use condoms with the Founding Fathers, saying they would be rolling over in their graves over that one.

It was enough to confuse some viewers, who couldn't quite follow her random leaps in logic and strange associations. But others found her bizarrely entertaining. At least she's consistently memorable.

"Late Show" airs weeknights at 11:35 p.m. ET on CBS.
