I'm assuming norks are covered by the 9pm watershed too.
Presumably growlers are too?
However, a recent 8pm evening episode of MiRABomer Murders had an artists model standing naked. She was turned so you could see her norks, but not her growler.
In the same scene, a painting of a model was shown. Admittedly, this was diagrammatic, but you saw norks AND growler.
Willies must be flaccid, you cannot show a stiff at all on TV.
