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. ("Another dream?") 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.
Also, his attempts to break the news. He tells Golde he has something important to tell her and she insists it can wait until after dinner. Then he tells her anyway, and gets more and more nervous, and when he gets to "I gave them my permission", he jumps up and runs out before Golde realises what he said, shouting, "I'll eat later!"
This exchange after Tevye plays devil's advocate for Perchik and Mordcha:
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:
"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."
"I'm losing my head. Someday it'll fall off altogether, and a horse will kick it in the mud and goodbye, Yente."
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!".
In the film, Tevye provokes a argument regarding the sale of a six-year-old or twelve-year-old horse, right after cheerfully saying that this issue had been resolved a while ago. The whole village then starts to join into the argument.
The build-up to what seems to be everyone cooing over Tzeitel and Motel's new baby, which turns out to really be about his sewing machine.
