Ferrell's 12-season run as Berta the housekeeper in Two and a Half Men had made her a favorite among fans of the hugely popular sitcom, as well as her fellow actors. When Ferrell passed, Two and a Half Men costars Charlie Sheen and Jon Cryer posted tributes to her on Twitter: Sheen called Ferrell "an absolute sweetheart [and] a consummate pro," while Cryer wrote, "Berta's gruff exterior was an invention of the writers. Chatty's warmth and vulnerability were her real strengths."
