Let's make this birthday one to remember.

51 years old (Born on August 05, 1973)

Happy Birthday, Sean Sherk—the original "Muscle Shark"! It's been years since your epic Lightweight Championship victory on October 14, 2006. Frankly, we're still amazed you didn't flex through the cage that night! You gave new meaning to cardio and relentless pressure—making opponents question their own conditioning (and maybe even life choices).

So today we celebrate a legend whose ground game was tougher than Monday mornings and as reliable as birthday cake at parties! You're timeless proof there's always room for celebrating superior wrestling technique... especially over candles waiting helplessly atop frosting.

Here's wishing you endless takedowns—and slightly slower aging submissions!
