ROTF! Sally Struthers would be another good choice for KE.
Wait a minute, what about Jeanine Garofolo as Bon Bon? Lighten her hair, and let it go frizzy. Would Julia Louis Dreyfus consider playing a role like that?
Lindsay Lohan is too young, but does have the same work ethic as Bon Bon.
Cloris played Lois’ mother, and landed on their doorstep to help Lois when she was pregnant. LOL, oh boy she “helped out”. I remember her in Young Frankenstein. Such a great comedic actress.
I’ve got it! Fran Drescher as BonBon. Doesn’t look like her (maybe “could” if we tried) but has the obnoxicity factor down pat!
