Batsman hits wicket but fielders don't notice

In this video, you could see the batsman whose hitting the wicket went unnoticed by the fielders and the bowler, Piyush Chawla. And, you know what’s the funny part?

It was the batsman on the non-striker’s end who was probably the only one to have noticed it, and later even picked up the bails to make sure no one notices.
