Let's make this birthday one to remember.

47 years old (Born on April 29, 1978)

Happy Birthday, Mike Bryan! You're the only guy who can say he spent most of his life sharing glory with someone else—and still ended up number one. Winning all four Grand Slams alongside Bob wasn't enough; you had to dominate Australia six times between 2006 and 2013 just to make sure everyone knew twins really do everything better.

Here's hoping your birthday celebration is as perfectly synchronized as your legendary doubles matches—minus any sibling rivalry over cake slices. May this year bring more aces off-court, endless laughs on it, and fewer people confusing you for Bob (though let's face it—that's inevitable). Cheers!
