Questions about some lines of a sitcom
I’m watching a old TV show called "The Golden Girls", and there are some lines I can't understand.
When Blanche is dating a younger man, she exercises so hard for looking younger. She said:“No pain, no gain. Gotta look good for Dirk. A man his age is used to a trim body with good tone.”
And Dorothy said:“Then buy him a Princess phone.”
I don't know why Dorothy said this.
When Blanche was praised by the younger man, she said:"I do believe the man said "gorgeous." I'm gonna live forever!"
Dorothy said:"Not outside of an institution."
What did Dorothy mean?
