Let's make this birthday one to remember.

49 years old (Born on May 09, 1976)

Happy Birthday, Spencer "The King" Fisher! You've always been a knockout—literally. With 24 wins under your belt, you've delivered more punches than the post office delivers mail. Your epic battles in the octagon are legendary; fans still talk about that unforgettable slugfest against Sam Stout at UFC 58.

Though you hung up your gloves back in 2012, your legacy remains timeless—just like those highlight-reel knockouts and slick submissions. Here's hoping this birthday packs as much punch as one of your famous left hooks (but with fewer bruises). Cheers to another year of being undefeated at retirement life!
