Let's make this birthday one to remember.

49 years old (Born on February 03, 1976)

Happy Birthday, Kim Dong-joo! You've swung for the fences countless times and fielded grounders smoother than my grandma spreading butter in her baking pan. Your legendary run with the Doosan Bears at third base not only scored you multiple Golden Gloves but also earned deep respect from teammates, fans, and aspiring youngsters alike.

And let's never forget that sparkling gold medal moment—winning it all as part of South Korea's historic team during baseball’s inaugural World Baseball Classic back in 2006. Keep inspiring us, champ; your legacy remains shinier than a freshly-polished golden glove—even after another candle-filled birthday cake!
