The Match for Africa has always been for a great cause, as spectators get to witness some tennis wizardry with profits going to charity.
On this occasion, over $2 million dollars were raised for the Roger Federer Foundation, headed by (you guessed it) the world No. 4 himself, for the fourth Match for Africa which took place on April 29.
But not before a moment of hilarity took place.
Playing against American John Isner in the best of three single's match, the second set saw Federer get hit in the back by Isner's serve. While it sounded like it hurt, The Swiss player shook it off in comedic style, feigning an old man with a crooked back and using his racket like a walking stick.
That led to roars of laughter from the crowd and Isner himself.
Watch: Federer acts like an old man
The Roger Federer Foundation is dedicated to improving education in Africa and in Federer's home country, Switzerland. It operates in many African countries, such as Botswana, Mawani and South Africa, and believes that the benefit of education cascades into many others, giving people the intelligence to tackle health and poverty.
Looks like to desire for charity matches cascaded into some unforgettable moments.
There were clearly no hard feelings between the two, with Federer taking to Twitter to thank Isner for his role in the event, saying: "Shoutout to @JohnIsner for helping make Match for Africa a success last night in Seattle 🙏"
The two were joined by their celebrity partners Bill Gates (Federer's partner) and Michael McCready (Isner's partner) for a doubles match for one set.
Gates' role was a big one as he is from Seattle, where the charity event was hosted, and worked closely with the Roger Federer Foundation to make the event happen.
McCready is the lead guitarist for the rock band Pearl Jam.
