Tennis champion Roger Federer refuses to let any ball go, including those that are out.
In his first round US Open match against Aussie Marinko Matosevic, Federer chased down a ball, smashed it between his legs and sent it straight into Matosevic's back.
Federer couldn't contain a chuckle and neither could a famous fan in the stands: basketball phenomenon Michael Jordan.
The Fed went on to win the match in straight sets.
