Let's make this birthday one to remember.

49 years old (Born on December 02, 1975)

Happy Birthday, Dennis "Superman" Hallman! It's safe to say the cage was your own personal Fortress of Solitude—except anyone stepping in discovered rather quickly you weren't exactly handing out hugs. Your dedication across three weight classes and more than 60 battles proves you're tougher than Kryptonite-coated granite.

From memorable submission holds showcasing your grappling wizardry to stunning fight finishes that had opponents wishing they brought their cape, you've inspired generations of athletes and thrilled fight fans for years. Here's hoping this birthday packs as much punch (and laughs!) as you've delivered throughout a legendary career. Fly high today, Superman!
