It all began when Katrina complained to Santoshi that Ranbir had stamped on her foot and didn't bother to apologise. She threw a fit, in protest. Santoshi walked up to Ranbir and told him that his behaviour was unacceptable, and since Katrina is senior to him he advised him to apologise to her.

Ranbir promptly walked up to Katrina and touched her feet, indicating that she was 'elder' to him. Upset at being called 'elder', Katrina was aflutter again and stormed to Santoshi. To prove that she was younger to Ranbir, she called up Rishi Kapoor, Ranbir's father, to check on Ranbir's age.

Santoshi was quite fed up when both the actors refused to calm down despite his repeated requests. Eventually, Ranbir and Katrina couldn't hold themselves any longer and burst out laughing. It was only then that Santoshi realised that he had fallen prey to their prank.
