[whistles]

On the way home tonight Zoë was singing (no words) Good-Night Ladies. (Probably because of an associations Bonny has built up in her mind.)

So, Bonny starts to sing it, with these words:

Good-night babies.
Good-night babies.
Good-night babies.
It's time to take a nap.

Zoë did not take kindly to it, and gave it some thought before she sang the reply.

That's not funny.
That's not funny.
That's not funny.
La la, la la, la.
