Henry Winkler was beside himself when Ron Howard left their beloved sitcom “Happy Days.” The “Arrested Development” alum, 79, and director, 71, starred on “Happy Days” together from 1974 to 1980.

In a sweet moment on stage, the pair hit the jukebox, and the “Happy Days” theme song began to play in an ode to the nostalgic tune.

Oh happy day. Ron Howard and Henry Winkler reunited with their “Happy Days” co-stars Anson Williams and Don Most for the first time in 50 years at Steel City Con in Pittsburgh on Saturday.
