Let's Do It (Let's Fall In Love)

When the little blue bird
Who has never said a word
Starts to sing
"Spring! Spring!"

When the little blue bell
In the bottom of the dell
Starts to ring
"Ding! Ding!"

When the little blue clerk
In the middle of his work
Starts to tune
To the moon up above

It is nature, that's all
Simply telling us to fall in love

Oh, yes
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 let's do it
Let's do it

Mama, let's fall in love
Oh, the Dutch in old Amsterdam do it
Not to mention the Finns
Folks in Siam do it
Just think of the 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

Oh, romantic sponges they say do it
Oysters down in Oyster Bay do it
Let's do it
Mama, let's fall in love

Cold Cape Cod clams 'gainst their wish do it
Even lazy jellyfish do it
Let's do it
Mama, let's fall in love

Electric eels, I might add, do it
Though it shocks them, I know
Oh, why ask if shad do it?
Waiter, bring me shad roe
In shallow shoals English souls do it
Goldfish in the privacy of bowls do it
Let's do it
Let's fall in love

Oh, dragonflies in the reeds do it
Sentimental centipedes do it
Let's do it
Mama, let's fall in love

Mosquitoes, heaven forbid, do it

So does every katydid do it
Oh, let's do it
Mama, let's fall in loveThe most refined lady bug do it
When a gentleman calls
Moth in your rug do it
What's the use of balls?
Locusts in the tree do it
Even the bees 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 the giraffes on the sly do it
Every hippopotami do it
Let's do it
Let's fall in love

Old sloths who hang down from a twig do it
Though the effort is great
Sweet guinea pigs do it
Buy a couple and wait
Now the world admits
Bears in the pits do it
Even Pekingeses in the Ritz do it
Let's do it
Let's fall in love
