Al Molinaro, who played drive-through and diner owner Big Al Delvecchio on the classic sitcom Happy Days and its spin-off Joanie Loves Chachi for a decade, has died at 96, CNN confirms. Molinaro joined the Milwaukee-in-the-’50s-set sitcom during the fourth season in 1976, after Pat Morita’s Arnold got married and left the show. Molinaro’s Delvecchio went on to appear in over 140 episodes. He uttered his sighing catchphrase, “Yep yep yep yep,” when things didn’t go his way … or sometimes when they did. The gregarious, jovial Al eventually became Fonzie’s uncle by marriage. Before Happy Days, Molinaro played police officer Murray Greshler on The Odd Couple. He also reprised the character in Weezer’s awesome music video for “Buddy Holly,” in which he’s still trying to cajole kids into trying the fish. Oh, Al.
