re: What is the most gut-wrenching scene on television?

ER had a couple during its peak.

“It’s Not Easy Being Greene”. Mother goes into eclampsia and for some reason in this massive hospital ER docs have to do the c section.

There is another episode where a guy is going into heart failure while on the transplant list. Heart gives out. Scenes where his daughter (8 or 9) stops Dr Greene in the room “why don’t you fix him”. End of the episode he crawls into bed with his own wife and kid and cries.
