Let's make this birthday one to remember.

71 years old (Born on April 10, 1954)

Happy Birthday, Peter MacNicol! From your brilliant portrayal of Dr. Larry Fleinhardt in NUMB3RS—where you made quantum physics seem almost understandable—to your unforgettable comedic timing as John Cage on Ally McBeal, you've consistently brought warmth and wit to every role.

Whether you're passionately explaining cosmic mysteries or charming audiences with quirky courtroom antics, your performances remain timelessly delightful. Here's wishing you another year filled with laughter, success, and perhaps fewer existential equations—but plenty more memorable moments!

Cheers to you today; may the coming year be as entertaining and inspiring as all the joy you've given us onscreen!
