They had planned to delete the part altogether if Paresh rejected the offer. Luckily for them, he not only agreed to do the 20 minute role, he also did it free of charge.
The role was that of Zandulal Tyagi, an RJ who hosts a hit show, Bahut Confusion Hai. Paresh liked the role when he heard about it and agreed to do it immediately without charging them, as he said that they are all Gujjus.
Himesh is glad Paresh did the role as he feels it would only have suited him. And he feels that it was kind of Paresh to do the role, even though he doesn't do cameos anymore.
