Let's make this birthday one to remember.

50 years old (Born on January 04, 1975)

Happy Birthday, Shane Carwin! The man whose fists are registered as lethal weapons and who once made the Octagon tremble with fear. Your legendary knockout power gave opponents nightmares—especially that unforgettable first-round demolition of Frank Mir to claim UFC Interim Heavyweight gold.

Even though you've stepped away from active competition, your legacy still echoes through MMA history louder than a heavyweight punch landing flush on fight night. May this birthday bring you joy equal to all those epic knockouts combined—and may no cake dare resist tapping out when you're around!

Cheers champ; here's hoping retirement hasn't softened your ground-and-pound skills against stubborn pickle jars!
