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 Lats 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, against 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
