A great line from the 1978 superhit Pati Patni aur Woh. I think this was the only comedy in the career of Baldev Raj Chopra (Yashraj Chopra's elder brother). He was more famous for his social films and thrillers. A standard tale (though uncommon at that time) of a husband, wife and the 'other' woman (the mistress), it also featured that very famous comedy song - ThanDe ThanDe paani se nahaanaa chaahiye".
The film starts around the time when Ranjeet Chaddha (Sanjeev Kumar) gets married to Sharda (Vidya Sinha). Ranjeet's friends tell him that in matters of the wife, the husband should always bat on the front foot and dominate her from the word go. They use a very quaint phrase for it - they call it "billii maarnaa" बिल्ली मारना.
Ranjeet takes their advice and constantly threatens Sharda. He tells her to do something quickly and ends the order with a very stentorian sounding
Whenever Sharda hears the 'varnaa' she completes the order on the double. However, one day when Ranjeet tells her that he has an early morning tour the next day and he wants hot water ready by 5 am. As is his wont. he adds the customary 'varnaa' in a threatening tone. Sharda loses her patience and turns around and asks Ranjeet
And a sheepish Ranjeet says
"वर्ना मै ThanDe paanee se hee nahaa लूंगा"
" varnaa maiN ThanDe paanee se hee nahaa loongaa"
So if you are being constantly bullied by someone - your boss, your spouse, your sibling - whoever. And you want to call his/her bluff, go ahead and say
