Don Quixote Volume 2, Chapter 67
Sancho rejoins Don Quijote and finds him under a tree where he has been busy nursing bitterness and disappointment. Don Quijote asks if Tosilos gave Sancho any news regarding the lovesick Altisidora -- is she still pining for him? Sancho says they spoke of other matters. Don Quijote brings up Sancho's unfinished whippings and how he'd like to see the squire's buttocks eaten by wolves. Sancho confesses he still can not make any connection between his buttocks and someone's disenchantment; nevertheless, he will keep his word but on his schedule.
As they pass the spot of their unlucky adventure with the bulls, Don Quijote muses on the idea of the young folks they had met there pretending to be shepherds. He tells Sancho that this is what they should do when they get back home. He sketches out a lovely idyllic existence and Sancho climbs right on board even suggesting that Carrasco, the Barber and the Priest might want to join them. Sancho suddenly starts to worry about his daughter's virtue being in danger in the hills and he spits out half a dozen proverbs. As Don Quijote complains about Sancho's overuse and abuse of these phrases, he ushers in a few of his own. Sancho points this out saying:
"...that what applies here is the old saying about the pot calling the kettle black." Volume 2, Chapter 67, pg. 716
