From the finale:
One of my favorite episodes is where Dorothy has a sort of snooty friend who fancys herself apart of the Miami literary scene. It turns out she's an anti-Semite and Dorothy lays into her good at the end.Sophia: I'm going to stay here with the girls.
Dorothy: (inquisitively) With the girls?
Sophia: (abrubtly) Blanche! Rose! Whatever they are.
And the one I imitate most often is when Rose has irritated the hell out of Dorothy somehow. Dorothy doesn't really react, and instead asks Rose to hand her the newspaper. Dorothy clarifies that she wants the Metro section and when Rose hands it to her Dorothy sops her upside the head with it. You probably have to see it but Bea Arthur's deadpan humor was the best!!
