Rabbi: A blessing for the czar? Of course! May God bless and keep the czar... far away from us!
After Tevye has given Hodel and Perchik permission to get married, he suddenly gets worried about what he is going to tell Golde. Perchik suggests that he tell her about the rich uncle Perchik will be staying with in Kiev. Tevye shouts that he doesn't need to be told how to handle his wife. However, as soon as Golde starts reacting badly to the news, Tevye immediately tells her about the rich uncle in Kiev.
This exchange after Tevye plays devil's advocate for Perchik and Morcha:
Avram: (gestures at Perchik and Mordcha) He's right, and he's right? They can't both be right.
Tevye: You know... you are also right.
Many of Yente's quotes:
Yente:Ah, children, children, they are your blessing in your old age. But my Aaron, may he rest in peace, couldn't give me children. To tell you the truth, Golde, he hardly tried.
Yente:: I'm losing my head. Someday it'll fall off altogether, and a horse will kick it in the mud and goodbye, Yente.
This exchange between Tzeitel and Golde:
Tzeitel: But Mama, the men she finds. The last one was so old and he was bald. He had no hair.
Golde: A poor girl without a dowry can't be so particular. You want hair, marry a monkey.
The whole scene at the wedding with Lazar Wolf telling Tevye he doesn't have to listen to his 'quotes' since he is not marrying his daughter, the subsequent fight (with Tevye pushing Motel down every time he stands up to intervene), culminating with Tevye calling Lazar's wedding gift chickens diseased and Lazar responding "You leave my chickens out of this!".
