This is yet another scene that one could classify as very archetypally lynchian.
We are presented with a fairly normal scene of a young girl at the doctor with her parents. One may conclude that this is a school checkup or some such thing. It is only when the dialog begins that the utter perversion of normalcy comes creeping down.
This doctor is advising the girl to masturbate her penis, not for the sake of pleasure but to stretch out the skin, all for the purpose of cutting it off and turning it into a cheap imitation of a vaginal canal. The mother looks on with enthusiasm, with understanding, with some twisted version of love and the glint in her eyes gives away her glee. Glee for she is finally getting a daughter 17 years after birthing her third son.
The hapless father shifts uncomfortable as he is presented with this conversation about his daughters need to masturbate, the need to tug a penis that will soon be inverted. All while the middling thought in the back of his head "how is this right" chips away at the last shred of his backbone, a constant reminder of how he can never stand up to his wife, how he cannot save his youngest son. This is the look of hope dying before our eyes.
