WATCH: Federer hits Monfils where it hurts in G.E.M.S. Life video
Joined by Elina Svitolina, the two friends enjoyed an interesting practice session.
Don't try this at home, kids!
On Saturday, Elina Svitolina posted a blooper of fiancé Gaël Monfils standing in the firing line of the couple's friend, Roger Federer, at the back of a practice court.
“I know it’s a big challenge for you, but try to relax your arm and you can do it," Svitolina said in the clip.
Federer proceeded to hit three tennis balls in succession in the direction of the Frenchman...
Youu can probably guess how it all ends. The third ball, no pun intended, hit Monfils in a decidedly less-than-ideal spot.
"Sorry," Federer offered an apology, while Svitolina broke down in laughter.
"Don't try this at home," Svitolina cautioned.
The trio is gearing up for Roland Garros, which kicks off in six days.
