INQUISITIVE KIDDIE*
As sung by Ben Albert

My youngest son, he's of a most inquiring turn of mind,
And answers to his questions it all puzzles me to find.
We started in a tram today; with anger I turned red.
The passengers all smiled aloud when my young kiddie said:

"Have you spent that tuppence mother gave you?
Ain't that woman's face like our dog Nell?
Why is it that you're always wearing whiskers,
And mother never does? Please, Daddy, tell.
Is it true that we descend from monkeys?
Now I look at you, it must be so.
But if you are a monkey, where's your tail gone?
Aye, Dad, don't you know?"

We gave a supper party and I let our kid sit up.
He promised that he wouldn't speak a word, the little pup.
But later on, the rascal, he for knowledge seemed to thirst.
In front of all the guests we had, these questions on me burst:

"Will these people here eat all the food up?
Ain't they had no dinner for a week?
Is that the soup that mother fetched from uncle's?
And why does she put red stuff on her cheek?
Where did mother first discover, you, Dad?
Was it in a Barnum-Bailey show?
And how did you become my little daddy?
Aye, Dad, don't you know?"

My daughter Kate's been on the shelf for years, but found a jay,
And so to see her married, we all went to church today.
The youngster started talking; I tried to turn him out.
He got beneath the fam'ly pew and then commenced to shout:

"Is it right that sister's found a josser?
Is it true he'll meet an awful fate?
Does he know that mother's going to live with them,
Just to see that things are going straight?
Does he know that sister's leg's a cork one?
I wonder if she's ever told him so?
D'you think he'll find it out and want this money back?
Aye, Dad, don't you know?"
