Let's make this birthday one to remember.

58 years old (Born on May 09, 1966)

Happy Birthday, Tim Donnelly! From your unforgettable role as firefighter Chet Kelly on "Emergency!"—the master of practical jokes and comic relief—you've always known how to light up a scene (and occasionally set it ablaze). Your impeccable timing and mischievous grin made every episode memorable; who else could make firefighting look so effortlessly funny?

Here's wishing you another year filled with laughter, joy, and perhaps fewer firehouse pranks gone wrong. May your birthday be as timelessly entertaining as the countless moments you've given us onscreen. Keep smiling brightly—we're all still laughing along with you after all these years!
