What does the joke about ruby shoes in The Great Lady Mercer mean?

I don't know if you have seen the comedy The Great Mrs. Mercer, which is a family comedy series jointly produced by Picrow and Amazon Pictures. It tells the story of an American housewife who woke up after divorce in 1950s and tried to become a rare female talk show actress. I think every girl should have a look. It's interesting and instructive. Women should not be confined at home. They should have their own thoughts and consciousness. Everyone should have the courage to leave their families to find their true selves. I think this life is more meaningful.

Did you find the last joke about ruby shoes in the third season of The Great Lady Mercer? What does this mean? Personally, I guess ruby shoes are from The Wizard of Oz, and the heroine wearing these shoes is Judy? Garland, Judy? Garland ranks first in the world? Gay godmother? What needs special explanation here is that she is the first celebrity to be liked and sought after by a large number of homosexuals, so Charles is almost a lesbian in disguise.

Also, during the previous tour, Charles lost his temper on the boat, and only Mickey went to find them in bed alone. Mickey asked if it was because his girlfriend Monica was angry. Charles answered seriously that she was just an excuse. Of course, Xia Chan heard that she left him. The agent fired her because she wanted to protect Charles. But why didn't the agent tell Charles about himself and let Mickey talk about Charles? Isn't quitting Mickey more like shattered glass? Probably because I'm looking forward to the fourth season.

In fact, sometimes our audience has too many ideas, maybe there are not so many jokes about rubies, and screenwriters and screenwriters may not have so many ideas, but the attitude of thinking is still very desirable. Finally, I want to tell you about Amway, which is really a very good play. I hope you can have a look at it when you are free.
