All those who have worked with Akshay Kumar know what a big prankster he is. No wonder, once fooled they stay on alert all the time when he is around. So were Vidya Balan and Amisha Patel on the sets of comedy-horror film "Bhool Bhulaiya" in Jaipur.

A unit member said: "Vidya had earlier fallen prey to Akki's prank while shooting for "Heyy Babyy". So she was determined not to get fooled again. So was Amisha."

Then one day, Akshay arrived on the sets with a man carrying a handycam. The man used to shoot Akshay all the time, even when the actor was having lunch or yawning or lazing around. They used to talk with each other a lot. And this went on for about 4-5 days.

Finally, Akshay introduced the man to his co stars as a reporter with a reputed television channel. Akki requested that the leading ladies give him interviews. Vidya and Amisha promptly obliged and spoke at length about the film, their roles and careers.

As soon as the interviews were over, the man went up to Akshay and the two started laughing aloud. That's when Akshay disclosed that the man was not a reporter but his physical trainer.

"The ladies were fuming, but at the same time they just couldn't stop laughing either. Everybody on the sets had a good laugh," the source said. The only one who didn't fall for Akki's prank was Shiney Ahuja, since he knew well that the man was Akshay's physical trainer.
