Earlier it was actor Emraan Hashmi who pulled a prank on the sets of 'Raja Natwarlal' and now its antagonist, Kay Kay Menon. Kay Kay, known for his serious demeanor, recently treated onlookers to his lighter side as he pulled a fast one on Kunal Deshmukh .

With the help of film`s assistant director, Kay Kay created a ruckus by picking up a fight with the staff of the hotel. He also managed to pull in some junior artist dressed up as a cop to be part of the prank. Unaware of the whole set-up, when Kunal tried to stop the brawl, the fake policemen stepped in and blamed him for not shooting peacefully. The joke was not revealed until Kunal walked away with the fake cops. It was a hilarious scene for the crew members and a big sigh of relief for filmmaker.

Said Kay Kay, "Since our film is about cons, I thought it would be fun to fool the cast and crew for real too. And the best part is that no one suspected me, as people think I'm a serious person."

UTV Motion Pictures` con-caper, 'Raja Natwarlal' also stars Humaima Malik, Paresh Rawal and Deepak Tijori. The movie is all set to release on August 29, 2014.
