Abby Brewster: Oh, no.
Martha Brewster: Oh, he's so happy being Teddy Roosevelt.
Abby Brewster: Oh... Do you remember, Martha, once, a long time ago, we thought if he'd be George Washington, it might be a change for him, and we suggested it.
Martha Brewster: And do you know what happened? He just stayed under his bed for days and wouldn't be anybody.

Mortimer Brewster: Now look, darling, how did he die?
Abby Brewster: Oh, Mortimer, don't be so inquisitive. The gentleman died because he drank some wine with poison in it.
Mortimer Brewster: Well, how did the poison get in the wine?
Martha Brewster: Well, we put in wine because it's less noticeable. When it's in tea it has a distinct odor.

Martha Brewster: We knew you'd find out about it in time.
