Riding A Bike Across A Tennis Net

In hold my beer news, this is a video of Scottish cyclist Danny MacAskill (previously) riding his bike across the length of a tennis net. What is he, practicing to be an extreme ball boy or something? Because that would make tennis a lot more exciting to watch. Right now the only thing to get excited about is players smashing rackets and yelling at the umpire, which happens far too infrequently for me to ever justify watching tennis.
