Even educated fleas do it

Let' s do it, let' s fall in love

In Spain the best upper sets do it

Lithuanians and Let' s 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

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...
