Let's make this birthday one to remember.

44 years old (Born on May 18, 1980)

Happy Birthday, Michael! From turning pro in 1999 to becoming a three-time doubles Grand Slam champion and Olympic silver medalist, you've served up countless memorable moments. Your swift volleys and playful antics on court have always kept us entertained—though we're still debating whether your racket skills or your sense of humor is sharper!

As you celebrate another year, may your day be filled with laughter, joy, and fewer double faults than candles on the cake. Keep volleying through life with style; after all these years, you're still acing it! Cheers to you—tennis legend by day, birthday champ by night!
