Lyrics:

I know a bundle of humanity,
She's about so high;
I'm nearly driven to insanity,
When she passes by.
She's a sunny little honey,
But oh so hard to kiss;
I'll try to overcome her vanity,
And then I'll tell her this:

I'm young and healthy,
And you've got charms;
It would really be a sin
Not to have you in my arms.
I'm young and healthy,
And so are you;
When the moon is in the sky
Tell me what am I to do?

If I could hate 'yuh,'
I'd keep away;
That ain't my nature,
I'm full of vitamin 'A,' say!

[Spoken]
Say kid! Now you go to it!

Peggy Sawyer:
To what!?!

Billy Lawlor:
Your first notes on Broadway!

Peggy Sawyer:
I'm young and healthy,
And you've got charms;
It would really be a sin
Not to have you in my arms.
I'm young and healthy,
And so are you;
When the moon is in the sky
Tell me what am I to do?

If I could hate 'yuh,'
I'd keep away;
That ain't my nature,
I'm full of vitamin 'A,' say!

I'm young and healthy,
So let's be bold;
In a year or two or three,
Maybe we will be
Too old.
