While shooting for Ramesh Taurani's 'Toh Baat Pakki'–prankster Ahmed Khan decided to play a hoax on the newcomer Yuvika Chaudhary with Sharman Joshi's help but little did he know that the joke would turn on him.

We come to hear that Ahmed Khan took the lovely Yuvika's cell phone and sent Sharman Joshi quite an intimate text. He then told Sharman to play along.

Reveals a source, "At first Sharman was a little shocked with the message but when Ahmed told him about the prank he was playing on Yuvika –Sharman was game and replied to the text and scared the clueless Yuvika. Ahmed even went a step further and told Yuvika that the industry was a dangerous place and that she should take care of herself."

Funnily enough Sharman then decided to turn the prank on Ahmed Khan and revealed everything to Yuvika and instructed her to play along and cry and run off the sets.

"Yuvika had to pretend to cry and ran off the sets into the van. Ahmed panicked and went to mollify Yuvika as the shooting was stalled, " adds the source.

After much convincing and apologizing the crew finally gave in and revealed to Ahmed that the joke was on him!
