Rhoda: Mary, girls who need big engagement parties are very insecure. I ought to know. I used to have them myself…without a fiancé.
Jonas: (who is by profession a paleontologist) Rhoda, has anyone ever told you you have very nice bones?
Rhoda: Huh, oh yeah? And I came already assembled!
Rhoda: You know, Mary, going to dinner with a paleontologist can be very embarrassing. The last restaurant we were at, he started reconstructing the bones of his duck.
Mary: (watching her father try to install a new lock on her door) I just hate to see you aggravated.
Walter Richards: Dear, when you're retired, aggravation is just about the only fun you have.
