Remember that viral video of Roger Federer playing William Tell and hitting a bottle off someone's head? Federer's first-round opponent at the Australian Open tried the same trick on Monday, only it was during a match, it was hit at a ball boy and he totally didn't mean to do it.
The video is from a longer clip of the match, so feel free to hit stop after witnessing the good-natured ball boy's close brush with a Wilson-induced headache.
As you probably guessed from Alexander Kudryavtsev's accuracy, he was unable to defeat Federer in Melbourne, losing 7-5, 6-2, 6-2.
