"Please, let me know where you and Bubba register for your china."
I am watching a old sitcom called The Golden Girls, and there is a line which I'm not sure about.
Dorothy's ex-husband Stan tells her that they may wind up in jail beacause of tax evasion.
Dorothy says:"Good, good. I want you to go to jail. And I want a big bald convict named Bubba to pick you for his girlfriend."
After meeting with the auditor, they know that they have to cough up $2500 in 30 days, otherwise they will get incarcerated.
Stan says:"Oh, my God. We're going to jail."
Dorothy says:"That's right, Stanley. Please, let me know where you and Bubba register for your china."
What does the "register for your china" mean?
