DADDY: That was before I was married.

DYLAN: When I grow up I want to marry Mummy.

DADDY: Did you know that somebody has already married her?

DYLAN: No.

DADDY: Who do you think married Mummy?

DYLAN: I don't know.

DADDY: Do you want me to give you a clue?

DYLAN: Yes. [Daddy points to himself.]

DYLAN: You?

DADDY: Yes.

'Gak' means 'duck' and is a corruption of 'quack'.

Isaac is saying 'Mama', 'Dada', and 'Gak'. We're not sure what 'Gak' means.

Dylan wrote and performed a song about Isaac: 'Isaac is a musical instrument. Isaac is a musical minstrument'. The word alternates between 'instrument' and 'minstrument' which Dylan and his parents think is really funny.
