Yuvraj Singh couldn't stop laughing when he saw his friend Harbhajan Singh completing the 'Keep It Up' challenge. In the challenge, he had to keep the ball bouncing on his bat while taking a pledge to stay at home until the pandemic gets under control.

"Thank you Yuvi, I promise to be at home till the time it is required to be," Harbhajan said in the video. Funnily, he used a miniature bat and a sponge ball.

"In these challenging times, I am committed to staying at home to prevent the spread of #Covid19 and will #KeepItUp as long as it is required. @souravganguly @anil.kumble @shikhardofficial @unitednations," he wrote.

Yuvraj had used a leather ball and a bat for the challenge, and while challenging Harbhajan he already knew the cricketer wouldn't do it properly.

He roasted his mate for the challenge and wrote, "When you know your childhood buddy so well! I knew he will not do cross bat."
