When the little bluebird

Who has never said a word

Starts to sing "Spring, spring"

When the little bluebell

At the bottom of the dell

Starts to ring, ding ding

When the little blue clerk

In the middle of his work

Starts a tune to the moon up above

It is nature, that's all

Simply telling us to fall in love

And that's why birds do it, bees do it

Even educated fleas do it

Let's do it, let's fall in love

In Spain the best upper sets do it

Lithuanians and Letts do it

Let's do it, let's fall in love

The Dutch in old Amsterdam do it

Not to mention the Finns

Folks in Siam do it

Think of Siamese twins.

Some Argentines, without means, do it

People say in Boston even beans do it

Let's do it, let's fall in love

Romantic sponges, they say, do it

Oysters down in Oyster Bay do it

Let's do it, let's fall in love

Cold Cape Cod clams, 'gainst their wish, do it

Even lazy jellyfish do it

Let's do it, let's fall in love

Electric eels, I might add, do it,

Though it shocks 'em, I know,

Why ask if shad do it?

Waiter, bring me shad roe!

In shallow shoals, English soles do it

Goldfish in the privacy of bowls do it

Let's do it, let's fall in love

Mosquitos, heaven forbid, do it

So does every katydid do it

Let's do it, let's fall in love

Dragonflies in the reeds do it

Sentimental centipedes do it

Let's do it, let's fall in love

The most refined ladybugs do it

When a gentleman calls

Moths in your rugs do it

What's the use of moth balls?

The locusts up in the trees do it

Even over-educated fleas do it

Let's do it, let's fall in love

The chimpanzees in the zoo do it

Some courageous kangaroos do it

Let's do it, let's fall in love

I'm sure giraffes on the sly do it

Heavy hippopotami do it

Let's do it, let's fall in love

Sloths who hang down from the twigs do it

Though the effort is great

Sweet guinea pigs do it

Buy a couple and wait!

The world admits bears in pits do it

Even Pekingeses in the Ritz do it

Let's do it, let's fall in love
