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 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
