India's and Pakistan's two most hot-headed guys Harbhajan Singh and Shoaib Akhtar were involved in this incident. It happened during an Asia Cup match in Sri Lanka, back in 2010. India were given a stiff 268-run target by Pakistan. Moreover, it was a must-win game for India to stay relevant in the tournament.
While chasing, India were cruising well at one stage in pursuit of the target. But after MS Dhoni and Gautam Gambhir got out despite having some considerable time in the middle, it looked quite a tough ask for the rest of the batters to come and try to get as close to the target as possible. Interestingly, the lower order of India kept their cool and sealed the match.
Notably, at the business end of the innings, Pakistan's speedster, Shoaib Akhtar, came to bowl the penultimate over. He was up against Suresh Raina and Harbhajan Singh. Harbhajan was trying to get Raina on strike when 7 runs were needed off 8 balls. But Shoaib decided to hit the hard lengths and both deliveries were over-the-shoulder bumpers, which denied Harbhajan a single.
It was at this moment, Akhtar and Harbhajan got involved in a verbal altercation. Post this moment, it ignited a fire within Harbhajan as he indicated to Akhtar that he would smash him out of the park. As a result, in the last over, Harbhajan Singh smacked a six, over the deep mid-wicket region, to snatch the victory for Team India. Now, both of them share light moments recalling this interaction.
