This has been noted elsewhere, and I didn’t get around to watching it until last night, but Yeardley Smith had a small role as the waiting room nurse on Mad Men this week.  (Oddly, especially for someone with such pop-culture juice, it hasn’t popped up on her IMDB page yet.)  She gets to tell off a guy who’s waiting for his wife to have their first kid.  He’s kind of a dick to her, hence the wry smile you see at right.
