"I told my mother-in-law that my house was her house, and she said, 'Get the hell off my property.'"

In this quote, Joan Rivers is using humor to convey a common stress between mothers-in-law and daughters-in-law. By saying that she told her mother-in-law that her home was her house, she is indicating that she is welcoming her mother-in-law into her home and treating her like household. Nevertheless, her mother-in-law's reaction of "Get the hell off my home" reveals that there is still a sense of territoriality and boundaries between them. This quote highlights the delicate balance of relationships in between in-laws and the underlying power characteristics that can exist. It also showcases Joan Rivers' sharp wit and capability to poke fun at social norms and expectations.
