Jack Turns 40 (Again): The Birthday That Never Gets Old

The Jack Benny Program — Broadcaster Transition (1948–1949) · Aug 13, 2026 · 29m

Aired: Feb 13th, 1949. It's Valentine's Day eve, which means it's also Jack's birthday — and the whole gang is determined to remind him, whether he likes it or not. Don Wilson serenades him with a fortune-cookie prophecy, Mary needles him about his real age next to Eddie Cantor's, and a stubborn audience heckler refuses to join the birthday chorus over a case of mistaken holiday loyalty. A cozy, gag-packed episode built entirely around the running joke that Jack Benny has been 39 for as long as anyone can remember.
