Help!

It has to be Hopscotch...I can't think of any other recently-read book where the scenario could be possible...

Anyone know the title of the book wherein a male character, arguing with a female character steps on the duck that she had been preparing for them to eat?

All I can remember is that they eat duck only once a week, that when he steps on it, he crushes the ribcage and that the female character remarks upon this to a friend, and that the argument turns to laughter.
