A 1956 refrigerator and a lot of question

Serious question:

Why is this 66-year-old refrigerator, built by General Motors, better than the refrigerators we have today?

Also, what the hell is Charlie’s name in the video? Charlie what?

Also, and I’m serious:

Is the woman in this commercial – now dead and buried – playing both parts?

Or are there two actors in this commercial, speaking with identical voices and speech patterns?
