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 Fins
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

Other verses I´ve seen in print follow:
In old Japan, all the Japs do it
Up in Lapland little Laps do it
Let´s do it, let´s fall in love

The chimpanzees in the zoos 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
Even eagles as they fly 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 - garcon de
"shad roe"

The world admits bears in pits do it
Even Pekingeses at the Ritz do it
Let´s do it, let´s fall in love

The royal set sans regret did it

And they considered it fun
Marie Antoinette did it -
With or without Napoleon
