Is this real? Is this even possible? We’ll probably never find out, but I’d like to believe the best tennis player in the world is capable of amazing skills such as this one.

The setup is simple: Federer’s coach is having a pop at him and his serving style, so after a few more practice shots he fires one into the sunroof of the coach’s new Mercedes-Benz.

He then gets another one in, and another, before some other guy tries and fails. Finally, the coach opens his car door to find dozens of tennis balls falling at his feet.

I believe Federer got at least one in the sunroof, but that’s about it. The rest are pure camera trickery because this is a viral video commercial for Mercedes-Benz. Still, it’s fun at the very least.
