What happens when in a bid to play a prank on someone you become a victim of the prank yourself? Well, the results are for you to see!

Warning: This piece of news may cause a kind of laughter that's good for the heart!

It all happened on the sets of Tips Films Kismat Konnection in Canada.

Now we all know that Kismat Konnection stars Shahid (Kapoor) and Vidya (Balan) in the lead. And the duo turned good friends while shooting for this film. Sharing good camaraderie, Shahid also discovered Vidya's weaknesses and decided to play an innocent prank on Vidya.

Shahid got to know that Vidya is petrified of spooky stories and ghosts and bought a horrifyingly frightful mask to scare the day lights out of her.

Came the time of night and Shahid stealthily tip-toed towards Vidya's room, knocked the door, expecting none other than Vidya to open the door!

Even the unit members were pretty excited to catch a glimpse of Vidya's reaction and eagerly waited outside Vidya's room to watch the fun. A source reveals, "The entire unit was waiting with bated breath outside Vidya's door as they were all in on Shahid's prank. But guess what happened?"

Well it was time for the joke to be on Shahid because it was not Vidya but her mother who opened the door.

Shahid was shocked out of his wits when he saw Vidya's mother, while Vidya's mother stood too stunned to react.

A unit hand reveals, "Vidya's mom didn't know it was Shahid who was behind the mask. She thought he was an intruder so she held on to him tightly and called for security. Of course when the security guys came, everyone cracked up because the entire unit was in on the plan as Shahid had taken everyone into confidence."

The entire unit burst into laughter and Shahid joined in on the joke by laughing nonstop! Guess this was a time when Shahid's Kismat was not Konnecting with him!
