Donny Most may be forever frozen in time as red-headed teen, Ralph Malph, in Happy Days, but more than four decades after leaving the show, he completely reinvented himself.
Viewers of the sitcom knew him as the witty jokester who was always trying to be as cool as the Fonz.
As it turns out, his alternative career after his Happy Days success might just make him that!
Donny quickly became a fan favorite with his signature catchphrase; "I still got it," and his nickname, Ralph the Mouth.
He had brilliant comedic timing and became the ultimate sidekick.
But Donny originally auditioned for the role of Richie Cunningham — which went to Ron Howard — however after seeing him perform, producers created a new role for him.
When he left the show in 1980, he'd starred for seven seasons but was ready to pursue other projects.
Donny worked steadily as a versatile actor and director, appearing in shows like Star Trek: Voyager and Murder, She Wrote, and he had a recurring role in Glee.
But he eventually discovered his true love wasn't acting.
In 2016, Donny switched to swing music and a year later began touring in a show called "Donny Most Sings and Swings," performing a host of '50s hits with a seven-piece backing band.
Just ahead of his 70th birthday, Donny had huge success with his full-length album "New York High," proving it is never too late to pursue your dreams.
He's been married to his wife Morgan Hart since 1982. They are proud parents and grandparents, even relocating from Los Angeles to Colorado to be closer to their family.
Season 21 of the hit reality show America's Got Talent premieres on Tuesday, June 2, including judges Howie Mandel, Mel B, Simon Cowell, and Sofia Vergara
