My grandmother would crack us up when my mother would cook for her and ask whether she liked it. She would say "yes, it's very good." The she'd make a face of disgust to us.

One time, in her 80s, we came home to find her standing on the dining room table cleaning the light fixture. My mother started screaming that she would hurt herself. My grandmother of course said she wouldn't have to do that if my mother would clean it once in a while.
