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
