Apparently "MacGruber" will have a lot of nudity. We're sure it'll be funny, too, but if the stars' appearances on late-night shows are indication, it's all naked Will Forte all the time. And while some naysayers on internet message boards may disagree, that's not bad thing. It all sounds hilarious. Forte appeared on Letterman last night and discussed the celery-filled nude scene that horrified his mother. He also broke out a clip he'd done for the "Late Show" back in 1998. No nudity though.
