Charlie Sheen had his trademark bowling shirts. Ashton Kutcher appears to be going with an even more casual look for his "Two and a Half Men" stint.
Kutcher -- who'll star as broken-hearted Internet billionaire Walden Schmidt on the revamped "Men" when it premieres on Sept. 19 -- strips down for Ellen DeGeneres on Monday's episode of "The Ellen DeGeneres Show."
It's a look he's sported before -- Kutcher, along with his new costars Jon Cryer and Angus T. Jones, flaunted their birthday suits in an ad for the series back in July.
As Kutcher explains to DeGeneres, since the ad has been "getting a lot of attention ... I just figured I'm going to do everything nude from now on."
Shhh -- nobody tell the Parents Television Council, because their heads just might explode.
