Let's make this birthday one to remember.

78 years old (Born on December 21, 1946)

Happy Birthday, Josh Mostel! From keeping Billy Madison hilariously in check as Principal Max Anderson to your unforgettable role as Arthur Brooks in Big Daddy, you've mastered the art of comedic timing. Your scenes remain timeless classics—who else could handle Adam Sandler's antics with such effortless charm?

Here's hoping your birthday is filled with laughter and joy worthy of a standing ovation from all those who still chuckle at your iconic performances. May this year bring you even more memorable moments—and perhaps fewer penguin hallucinations than Billy experienced! Cheers to another fantastic trip around the sun, Josh!
