As someone who is a budding special effects artist, let me thank you for this pic, General!

Usually when doing a full head cast, the subject's mouth remains closed, but judging by the tube, I'm guessing she's being cast here for some sort of 'love doll' type thing.

Maybe she read my suggestion to Jeff in the Fan Requests section about selling life casts of disembodied pornstar heads for home Gag Factor fun?
