Shah Rukh Khan has revealed that many scenes from his 1995 film 'Dilwale Dulhania Le Jayenge' were improvised on the sets. "There was this scene with Amrish Puri where he was feeding...pigeons. [We] had this really funny scene where we're both awkwardly going 'aao, aao' to...pigeons. It's call for pigeons I'd heard in Delhi, so I added it," he said.
