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 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 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
