When a bird young and free
Hangs around a certain tree
Singing serenades that tell his love is true
That's because it's the natural thing to do

And when a cat on a fence
Keeps his darling in suspense
And he's brave enough to face a well-aimed shoe
That's because it's the natural thing to do

And you know every dove
Has it's heart set on love,
Rabbits, too, pet and pat,
And there's nothin wrong with that!

When a boy such as I
Tries so hard to qualify
With a very lovely lady such as you
Can't you see it's the natural thing to do?

And then the girl she acts demure
The boy he feels proud and sure
So proud and sure that he impulsively suggests a rendevous
Fine thing!
That's because it's the natural thing to do

But the girl she just won't agree
She whimpers and she simpers
And he begs on bended knee
But she runs away because she knows full well he'll pursue
The chump!
That's because it's the natural thing to do

Then the boy in despair
Waves his arms, tears his hair
Stamps his feet and he acts like mad
Then you know that he's got it bad

Then the girl she oughta fall
If she's got a heart at all
She should take him in her arms
And kiss him too
Oh! Oh! Just the natural thing to do
