An outstanding film. And the dialogue writer is one of the greatest dialogue writers of Hindi films. This is a scene that just precedes the breakdown of relations between the couple. Subir walks into the drawing room and talks to his secretary Chandru. 

Subir: kyon re chandru, museebat Taali?

Chandru: kaun? income tax vaali?

Subir: Haan.

Chandru: Bhai, returns to file kar diye hain, do chaar certificate nahin mil rahe yaar.

Subir: kyon?

Chandru: vo kehte hain, ki pichhle saal ki raqam, is saal mein Daalein.

Subir: arre ye kaise ho saktaa hai, ye to ek dam safed jhooth hai!

Chandru: Bhai ye kaala baazaar hai, isme.n safed jhooth hii chaltaa hai!

भाई ये काला बाज़ार है, इसमें सफ़ेद झूठ ही चलता है!

Not much has changed in Bollywood since! :)
