Bollywood's biggest prankster, 'Shivaay' actor Ajay Devgn, in the presence of wife Kajol brings out his super naughty side on TKSS.

Ajay and Kajol will appear on the show this weekend on 'Diwali Special' and the action star turned totally 'nasty' when it came to play games.

Ajay first offered to teach Kapil and Chanadan Prabhakar a trick.

Ajay took a coin and placed it on hus forehead, he also fixed a cup in his pants right below... he then slowly looks down in order to drop the coin right into the cup.

Eveyone claps and then it was Kapil Sharma to give it a try.

Clad in ethnic wear, Kapil was shy though since he had to pull up his kurta to do the same.

Well, he managed too.

Now it was Chandu's turn and no one could have imagined there was a twist about to happen.

Ajay was standing near him during the act and.....! Something that left everyone in splits including Kajol.

Ajay himself posted the video with the message, "For those who've been saying- "we hear you're a prankster, but never seen anything"- pulled one yesterday at The Kapil Sharma Show."
