Sunshine
It is without a doubt that the novel is filled with instances of the narrator's humorous discussions. One of those is the discussion about sunshine. When Dora gets told that the sun shines on her she jumps into an ironic discussion about sunlight's insincerity, about how the sun shines on everyone, therefore its sunshine isn't sincere. She concludes it to be the most democratic thing she's ever seen. This personalization of sunshine makes one believe that Dora is talking from experience and that sunshine is a metaphor for a person perhaps.
Chronicler of all the Hazards
Dora ironically concludes that while she is gathering notes for her own biography, she inadvertently became a chronicler of all the Hazards, whose blood flows through her veins, but whose name she managed to get hold of. She concludes that this career will go unnoticed by the dynasty of Hazards, just like her and Nora were unnoticed as biological members of it.
Melchior's irony
Melchior's obsession with following in his father's footsteps and following his father's dreams is described in a ridiculous and filled with undertones of irony way. There is at first this obsession with his father's plastic crown, from him performing as King Lear. This crown is his most prized possession, more important than the lives of his true daughters, as shown in the scene where his house burns in fire. His dream of making in the Hollywood with Shakespeare, to make his father's dream everybody's dream is ironically concluded with his desire to make awful a lot of money as well.
