When the little blue bird who has never said a word
Starts to sing "spring, spring"
When the little blue bell in the bottom of the dell
Starts to ring "ding, ding"
When the little blue clerk in the middle of his work
Starts to tune to the moon up above
It is nature that's all
Simply telling us to fall in love (oh yes)
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, mama let's fall in love
Oh 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
Oh romantic sponges, they say, do it
Oysters down in Oyster Bay do it
Let's do it, mama let's fall in love
Cold Cape Cod clams, 'gainst their wish, do it
Even lazy jellyfish, do it
Let's do it, mama 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 (ohhh)
The dragonflies in the reeds do it
Sentimental centipedes do it
Let's do it it, mama let's fall in love
Mos-qui-tos, heaven forbid, do it
Soon as every katydid do it
Oh let's do it, mama lets' fall in love
The most refined lady bugs do it
When a gentleman calls
Moths in your rugs do it
What's the use of moth balls
Locusts in trees do it
Why even a bees do it, even over-educated fleas do it
I let that do it, let's fall in love!
Ask that the chimpanzees in the zoos do it
Some courageous kangaroos do it
Let's do it, mama let's fall in love!
Ooh, fall in love
I'm sure that giraffes on the sly do it
Heavy hippopotomi do it
Let's do it, mama let's fall in love
Old sloths who hang down from the twigs do it
Though the effort is great, yes
Sweet guinea pigs do it
Buy a couple and wait!
Now the world admits bears in the pits do it
Even pekingeses in the Ritz do it
Let's do it, mama let's fall in love!
