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

When the little blue birds who have never said a word
Start 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 its 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 Letts 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, mm
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 'em I know
Oh, why ask if shad do it
Waiter, bring me shadroe
In shallow shoals, English soles 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
Baba-da, ta-ti, das
Mosquitoes, heaven forbid, do it
So does every katydid do it
Oh, let's do it
Mama, let's fall in love

The most refined ladybug do it
When a gentleman calls
Moths in your rugs do it
Well, let me ask, what's the use of balls? Mm
Locusts in the trees do it
Why, even the bees do it
Even all educated fleas do it
Let's do it, let's fall in love

I said the chimpanzees in the zoo do it
Some courageous kangaroos do it
Let's do it
Mama, let's fall in love
Oh, fall in love
I'm sure that girafes on the slide do it
Every hippopotami do it
Let's do it
Mama, let's fall in love

Oh, sloths who hang down from the twigs do it
Though the effort is great
Yes, sweet guinea pigs do it
Buy a couple and wait
Now the world admits bears in the pits do it
Even pekigneses in the Ritz do it
Let's do it
Mama, let's fall in love
