While shooting in Toronto at the community centre location, Vishal Malhotra (who is playing Shahid's friend) thought his shoot for the day was done and he left for the hotel which was about a ten minutes distance from location.
Just then Aziz Mirza decided that he wanted to shoot one more angle and called for Vishal. However, he was informed that he had left. Shahid called up Vishal and asked him to come back. He also told him that the shooting has stopped and both Ramesh Taurani and Aziz Mirza were very upset that he had left the set. He told everyone to play along with this.
So when Vishal literally ran back to the location he first met Vidya who cordially just greeted him, hence making him even more nervous. Then Shahid took him aside and building up the tension told him that this was not done and now he was in trouble.
As poor Vishal came onto the set, everyone just gave him stern looks. He was so scared and kept apologizing but Rameshji gave the joke away when he could not control his laughter and Vishal realized that everyone was pulling his leg.
"I can't believe that I actually fell for it. They all held up well. Thank God for Rameshji who gave the joke away. I was so very nervous. Shahid and i have known each other from Ishq Vishk days and we keep pulling these wise ones on others but I never expected him to pull this one on me. Look out Shahid, I owe you one," he says jokingly.
