God, yes, I love that scene! And while on one level it's so very moving, on another he's talking about the cynical manipulation of our most powerful and intimate human emotions in order to sell a gadget.
I've been watching that 90's show, Homicide, again lately. Lots of great moments from that series. One in particular: When a middle-aged detective, Crosetti, turns up drowned in the bay, his young partner Lewis is determined that what looks like a suicide will be ruled a homicide (though everyone but Lewis is pretty sure it's suicide.) Well finally the M.E. report comes in, saying that Crosetti had massive amounts of tranquilizers, pain-killers, and whatnot in his blood at the time of death. So Lewis breaks down and cries! I don't know why, but this really shocked me the first time I saw it.
