| 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, «Ting, ting» | 
| When the little blue clock in the middle of his work | 
| Sings a song 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 let’s 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 | 
| 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 | 
| Against 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 bring me shad roe | 
| Come on and bring me, 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 | 
| Now if the birds and the bees and the trees do it | 
| The monkeys and the birds, bees do it | 
| In, in water gates they quarrel but they do it | 
| And if they can make up and still do it baby, how about me and you? | 
| Hey let’s do it now | 
| Let’s do it, let’s fall in love | 
| 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 |
