The Life and Opinions of Tristram Shandy, Gentleman Book 5, Chapter 32 Summary
But the fifth commandment, Toby tries to interrupt … and then commands Trim to recite up to the fifth commandment. Mr. Shandy scoffs and asks Trim what exactly he means by "honouring thy father and mother."
Trim explains that it means to support them financially when they get old. Yorick shakes his hand in appreciation.
