Rajeev Khandelwal is an atheist in his real life. When Khan asks him before his third dare whether he believes in Khuda (God) or not, he immediately answers in the affirmative.
Whilst through the film Rajeev Khandelwal and Tina Desai are assumed to be victims of Paresh Rawal's "tests", the climax of the film safely concludes they were the actual villains of the movie all the while.
Rajeev Khandelwal initially was opposed of kissing Desae for one of their tasks, but eventually he complied.
The music used in End credit of this movie has been taken from the OPENING CREDITS of THE DAY AFTER TOMORROW. Whether its an inspiration(read copy) or an official release is still not clear.
