A woman goes to her rabbi with a serious problem. Her two female parrots have picked up a bad habit. Any time she has visitors, the two parrots embarrass her by saying, in unison, "Hi ! We're prostitutes. Want to have some fun?"
To her surprise, the rabbi breaks into a smile, explaining that he has two male parrots which he has trained to pray and who've become very observant, spending much of the day praying in their cage. He's confident that if the woman brings her two parrots over to his house, his two parrots will exert such a positive influence that her birds will turn into model parrots.
The next day the woman drives over to the rabbi's house and brings her two parrots into his home. As she looks around, she notices a large cage with two parrots, each wearing a little kippah and tiny tallis and each holding a miniature siddur, while they rock back and forth in prayer. Sure enough, as soon as she places her female parrots in the cage, they shout out to their male counterparts "Hi! We're prostitutes. Want to have some fun?"
One of the rabbi's parrots immediately turns to the other, squawking: "Moishe, put the damn book down. Our prayers have been answered!"
