Watch | Umpire Chris Gaffaney hilariously tries to troll Pujara and Hazlewood

In the 140th over of the Indian innings, with Josh Hazlewood bowling to Cheteshwar Pujara, on-field umpire Chris Gaffaney provided the fans with a light moment after a slow start to Day 4. Pujara, who was batting on 142, attempted to play an uncharacteristic hook but missed the ball by quite a distance. 

The Aussies, who appeared to be frustrated with the partnership, decided to put in a weak appeal. To everyone's surprise, Gaffaney started raising his finger. However, the finger ended up on his head as he started scratching his scalp through his hat. While Hazelwood did not appeal, he had to turn behind after seeing Steve Smith, standing at first slip, with a confused expression on his face. 

Gaffaney's partner on the field, Ian Gould couldn't stop himself from smiling while third umpire Nigel Llong was seen struggling to control his laughter in his box. Pujara, however, looked like his usual calm knowing fully well that he had not gotten anything on the ball.

On a day that has not seen too much action, it appears the umpires have decided to take matters into their own hands to provide some entertainment for the viewers.
