Let's make this birthday one to remember.

81 years old (Born on June 08, 1944)

Happy Birthday to the unforgettable Don Grady, our beloved Robbie Douglas from "My Three Sons"! Your charming presence and comedic timing turned everyday family chaos into pure television gold. Whether dealing with brotherly antics or winning us over as a talented musician, you set the standard for classic sitcom sons everywhere.

Even beyond your iconic role on-screen, you've continued to showcase remarkable success off-camera too—your musical talents enriching so many lives along the way. Here's hoping today brings endless cake and laughter (just keep Uncle Charley away from catering duties)! Wishing our favorite son a timeless birthday filled with joy!
