New ‘Shameless’ Teaser Shows Off William H. Macy’s Translucent Butt (Video)

Season six of Showtime series premieres Jan. 17

In a new teaser for Showtime’s “Shameless,” William H. Macy bares it all — and what a sight it is.

In the clip from the series’ upcoming sixth season, Macy’s Frank Gallagher is walking through his kitchen when his son Ian (Cameron Monaghan) happens to notice that Frank is wearing a half t-shirt and women’s panties.

In another, Kevin (Steve Howey) has some questions for Carl (Ethan Cutkosky) after he gets out of juvenile detention, specifically if the kids inside trade sexual favors. “That’s what everybody’s thinking, right?” he says.

Macy and Emmy Rossum star in the series, which follows Chicagoan Frank Gallagher as the proud single dad of six smart, independent kids, who have grown up well in spite of him.

Season six of “Shameless” premieres on Jan. 17 at 9 p.m./8c.

Watch all four teasers.
