HAPPY DAYS ARE HERE AGAIN!

Henry “The Fonz” Winkler has raced to the rescue as the new exec producer of “Hollywood Squares,” and his first idea to save the dying program was ringing up his old “Happy Days” friends. The showbiz veteran asked them to join him for a weeklong reunion on the quiz show. The Fonz got a big thumbs-up from Tom Bosley, Marion Ross, Anson Williams, Donny Most, Erin Moran, Pat Morita and even busy director Ron Howard. It’s hush-hush but there’s even more good news: Winkler’s also trying to land the schlemiels and schlimazels of “Laverne & Shirley.”
