Lyrics:

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
