There are often some strange noises heard on a tennis court.
However, usually they are the grunts of the players involved.
It was different for two players at the Sarasota Open in Florida this week.
Frances Tiafoe and Mitchell Krueger were battling it out, when they were interrupted by groaning...of a different kind!
Watch the video below:
Both players and the crowd knew exactly what was happening.
The poor innocent kid in the crowd being told by his mother to cover his ears completes the video!!
