Australian cricket greats Shane Warne and Kerry O'Keeffe took a light-hearted dig at Indian wicketkeeper Rishabh Pant who took to the field on day two of the fourth Test wearing some bizarre-looking sunglasses.

Pant, who blasted 97 from 118 deliveries during the second innings of the SCG Test earlier this week, opted for a pair of fluoro yellow and blue sunglasses, which came as a shock to both Warne and O'Keeffe.

After replays showed a close-up of Pant's questionable look on day two, Warne immediately asked his fellow cricket great and commentary partner whether the pair of sunglasses came from a service station.

"What do you think of those shades that Rishabh Pant is rocking?" Warne asked O'Keeffe on Fox Cricket.

"Straight out of the service station?"

O'Keeffe, who's well known for having a laugh at anything amusing, jokingly said he was adamant they were a pair purchased form a local service station.

"They are servos, aren't they?" O'Keeffe replied.
