But 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 mens, 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

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

Mosquitoes, heaven forbid, do it,
So does every katydid 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?

Locusts in trees do it,
Bees do it,
Even overeducated fleas do it,
Let's do it, let's fall in love

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