Nana

Leo, did you give Helen the fifty dollars?

Leo

What fifty dollars?

Nana

Your father won a thousand dollars at the track last week, and he gave you a hundred, and you were supposed to give fifty dollars to your sister.

Leo

Ma, dad died in nineteen-sixty-two.

Leo

(laughing off Nana's confusion) Believe me. I don't owe your mother fifty dollars.
