When the little bluebird
Who has never said a word
Starts to sing Spring Spring
When the little bluebell
in the bottom of the dell
Starts to ring Ding Ding
When the little blue clerk
In the middle of his work
Starts a tune to the moon up above
It is nature that's all
Simply telling us to fall in love
And that's why 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
