Saturday is an important day in the sports world. No, it's not the Super Bowl. Or the Wimbledon championship match. Or the Masters. Instead, Saturday, Sept. 26, 2015, marks the 34th birthday of one Serena Williams -- 21-time Grand Slam winner, two-time Serena Slam crown holder and the G.O.A.T. of the women's tennis world.
Calendar-year Grand Slam or not, Williams has had a remarkable season. So to commemorate Queen Serena's special day, we put together 34 of the reasons why we love her.

(Start at 5:30 in the video.) “Um, it’s 11:30. To be perfectly honest with you, I don’t want to be here. I just want to be in bed right now, and I have to wake up early to practice, and I don’t want to answer any of these questions, and you guys keep asking me the same questions, so it’s not really making it super enjoyable. Just being honest.”
