The Gabor sisters actually did some acting. Granted they acted pretty much as themselves but they made it work.
IIRC, one of them frequently voiced characters in the 60s and 70s Disney animated features. It would be a real shocker to tell a kid te true nature of the voice behind numerous Disney classics.
There was also "Mama Gabor" who tried to keep up with the daughters.
Once on the Tonight Show Johnny Carson asked Zsa Zsa Gabor if she could confide in him and tell him which of the Gabors was the oldest. She answered "Well you'll never get her to admit it, but it's Mama".
