The Twelve Chairs1970

Father Fyodor:
[Bender is masquerading as a government official as Father Fyodor walks into the office to get information about the chairs] I am Vorobyaninov's son. [Ostap stares at him] His first-born. He was like a father to me.

Ostap Bender:
So... you are Vorobyaninov's son.

Father Fyodor:
Yes, I am.

Ostap Bender:
[quickly] How old are you?

Father Fyodor:
46... 44.

Ostap Bender:
Which is it?

Father Fyodor:
42... 42.

Ostap Bender:
According to our records, Vorobyaninov is 53. That means that when you were born, your father was... 11. [Father Fyodor gives an impressed whistle]
