Film : Sholay
Year of release : 1975
Spoken by : Jay (Amitabh Bachchan)
Spoken to : Veeru (Dharmendra)
Veeru and Basanti (Hema Malini) are now a proper romantic couple. Veeru wants Jay to go to Basanti's mausee (aunt) and ask for Basanti's hand. Jay is very skeptical of Veeru's 'love' and his desire to 'marry'. See how the scene opens.
Veeru : Jay...
Jay : hmmm...
Veeru : aaj maine kuchh sochaa hai...
Jay : hmm...kabhii kabhii ye kaam bhee karnaa chaahiye
The sardonic Jay is heaping scorn on Veeru and his ability to think. I do loads of this 'kaam' and wish more people in this world would do so too. :)
As Jay says,
हम्म... कभी कभी ये काम भी करना चाहिये
