But 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 Lets do it,
Let's do it, let's fall in love.

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.

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.
[ Lyrics from: http://www.lyricsfreak.com/a/alanis+morissette/lets+do+it+lets+fall+in+love_20928246.html ]
Electric eels, I might add, do it,
Though it shocks 'em I know,
Why ask if shads 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.

The dragonflies in the reeds do it,
Sentimental centipedes do it,
Let's do it, let's fall in love.

Mosquitoes, heaven forbid, do it,
So does every katydid do it,
Let's do it, let's fall in love.

The most refined ladybugs do it,
When a gentleman calls,
Moths in your rugs do it,
What's the use of moth balls?

Locusts in trees do it,
Bees do it,
Even overeducated fleas do it,
Let's do it, let's fall in love.

Let's do it, let's fall in love,
Let's do it, let's fall in love
