Film : Dil Chaahta Hai
Year of release : 2001
Spoken by : Sameer (Saif Ali Khan)
Spoken to : Pooja (Sonali Kulkarni)
Dialogue writer : Farhan Akhtar
Sameer is against arranged marriages. But his parents have called over a family home and want him to meet the daughter Pooja for a possible alliance.
His father asks him to take Pooja into his room. Pooja's father also agrees to this proposal. And the both of them land up in Sameer's room. He doesn't know how to deal with her. So he shows her a framed photo featuring him and two of his friends.
"ye aakaash hai aur ye sid."
A polite Pooja responds with
"gehri dostii lagtii hai"
Sameer responds with a line which has now been established as classic Farhan Akhtar humour. At that time it might have been denounced just as a PJ (a poor joke).
"haa.n yaa to dosti gehri hai, yaa ye photo 3D hai"
"हां, या तो दोस्ती गहरी है, या ये फ़ोटो 3D है"
