Let's make this birthday one to remember.

39 years old (Born on January 16, 1986)

Happy Birthday, Mason Gamble! From your mischievous antics as Dennis Mitchell in "Dennis the Menace," you've taught us all that a slingshot and innocent grin can conquer any grumpy neighbor. Your timeless portrayal still brings laughter to families everywhere—proof that childhood mischief never goes out of style.

As you celebrate another year, we applaud your journey from playful troublemaker to accomplished actor and marine biologist. Whether charming audiences on screen or exploring ocean depths off-screen, you've shown versatility worthy of applause (and perhaps fewer broken windows). Here's wishing you continued success—and may your birthday cake remain safe from slingshots!
