Mr. Irving Berlin
Often emphasizes sin
In a charming way
Mr. Coward we know
Wrote a song or two to show
Sex was here to stay
Richard Rodgers it's true
Took a more romantic view
Of this sly biological urge
But it really was Cole
Who contrived to make the whole
Thing merge

He said the Belgians and Greeks do it
Nice young men who sell antiques do it
Let's do it, let's fall in love
Monkeys whenever you look do it
Aly Khan and King Farouk do it
Let's do it, let's fall in love
Louella Parsons can't quite do it
For she's so highly strung
Marlene might do it
But she looks far too young
Each man out there shooting crap does it
Davy Crockett in that dreadful cap does it
Let's do it, let's fall in love
Our famous writers in swarms do it
Somerset and all the Maughams do it
Let's do it, let's fall in love
The Brontes felt that they must do it
Ernest Hemingway could—just—do it
Let's do it, let's fall in love
E. Allan Poe-ho! ho! ho! did it
But he did it in verse
H. Beecher Stowe did it
But she had to rehearse
Tennessee Williams self-taught does it
Kinsey with a deafening report does it
Let's do it, let's fall in love

In the Spring of the year
Inhibitions disappear
And our hearts beat high
We had better face facts
Every gland that overacts
Has an alibi
For each bird and each bee
Each slap-happy sappy tree
Each temptation that lures us along
Is just Nature elle-meme
Merely singing us the same
Old song
In Texas some of the men do it
Others drill a hole-and then do it
Let's do it, let's fall in love
West Point cadets forming fours do it
People say all those Gabors do it
Let's do it, let's fall in love
My kith and kin, more or less, do it
Every uncle and aunt
But I confess to it-
I've one cousin that can't
Teenagers squeezed into jeans do it
Probably we'll live to see machines do it
Let's do it, let's fall in love

Each baby bat after dark does it
In the desert Wilbur Clark does it
Let's do it, let's fall in love
We're told that every hormone does it
Victor Borge all alone does it
Let's do it, let's fall in love
Each tiny clam you consume does it
Even Liberace—we assume—does it
Let's do it, let's fall in love!
