When Cliff Arquette brought his homespun Charley Weaver persona to The Hollywood Squares, it was the second unlikely revival of an entertainment career that stretched back to radio days. Despite retiring in the ’50s, a surprise Tonight Show shout-out from Jack Paar thrust Arquette and Weaver back into the spotlight—though in this second act, the actor and his frumpily dressed character from “Mount Idy” became one and the same. The Squares’ one-liner prompts didn’t afford enough space for Charley’s rambling, character-driven, malapropism-ridden “Letters From Mamma” bit, so Arquette’s creation was given a new fictional place of residence: a retirement home. The implication of advanced age and Arquette’s personal areas of expertise made Charley the go-to panelist for historical questions on Squares, and his bluffs and joke answers frequently drew details from “life at the home.” A 1973 stroke kept Arquette out of his lower-left square for a time, but he would return to the show prior to the lethal stroke he suffered in 1974. Forty years on, the extended epilogue to Arquette’s career continues apace: He’s the grandfather of actors Rosanna, Patricia, David, Alexis, and Richmond Arquette.
