Yea, there's a scene in the latest season that involves her character breast feeding a grown man (who's the show's parody of Superman, and also kinda alt-right leaders/politicians, no less).
What strikes me as particularly dumb, apart from not recognising that the show is satire, is that her character's motivation was to get ahead by pleasing the man in charge. Which means, even if she were in character, and ok with the ridiculous idea of providing or pretending to provide breast milk, she'd have no interest in providing any breast milk to anyone.
