Frances Conroy, of Six Feet Under fame has been cast on Grey's Anatomy in a guest role that sounds perfectly suited for the Golden Globe winner's talents, according to TV Guide.

She will portray a patient named Eleanor who blacks out. Why?

Because, as Grey's Anatomy creator Shonda Rhimes explains, Eleanor claims she blacked out right around the time she raced into a Laundromat and caught her naughty husband folding another woman's panties. Yeah, that will do it to you every time.

"Whether or not she really blacked out is an issue," says Rhimes.

Interesting. Detectives Grey and Yang will have to investigate.
