Video! Ashton Kutcher Tells Letterman 'Men' Will 'Go Through the Roof'

"Two and a Half Men" star Ashton Kutcher walked on to the "Late Show with David Letterman" wearing a helmet and bulletproof vest with a sign that said, "Not Dave," as a joke regarding recent threats made against the talk show host.

The sitcom star spoke highly of his new gig on "Men," which airs next month, saying, "I think it'll go through the roof, I really do. I've been laughing really hard."

Ashton confirmed Sheen's character does die on the show, but could not go into detail. "He dies because he's no longer living."

Kutcher expressed his excitement at returning to sitcom work, five years after "That '70's Show" ended.

When Letterman cracked a Charlie-related joke, asking if Kutcher prefers "strippers or porn stars," the actor responded on a more serious note, saying, "I have a foundation that fights human trafficking."

Catch Ashton on "Letterman," airing Thursday on CBS.
