Flit-man, spare that fly!

'Tis the season for universal compassion, extended even to the wee beasties among us. Hence this musical excerpt from the 1930 film Just Imagine, a science fiction fantasy in which a fellow wakes to find himself fifty years in the future, in 1980. (Imagine that!)

The song is Never Swat a Fly by DeSylva, Brown & Henderson, performed by Frank Albertson and Marjorie White aboard a wondrous, state-of-the-art mode of travel called... a dirigible! Why Frank and Marjorie are ruminating on this particular subject is unknown to me; I've not seen the complete film. If the verse is to be believed, love explains all, but one suspects they've been reading Robert Burns, or studying up on Buddhism. I've heard this sermon before, delivered in 1992, sans verse, by those eminent theologians Marty Grosz, Keith Ingham and their Hot Cosmopolites, but here it is in its original incarnation:

FRANK:

Love has made me tender, I now appreciate

Ev'ry little creature on this Earth that has a mate.

Once I hated crickets, I couldn't stand a bee,

Now here is the motto that I follow faithfully:

Never swat a fly,

He may love another fly,

He may sit with her and sigh the way I do with you.

Never harm a flea,

He may have a favorite she

That he bounces on his knee the way I do with you.

Never stop a bee if he is going anywhere,

You may be concluding some terrific love affair, be careful!

Don't step on an ant

In the middle of a pant,

He may want to, but he can't the way I do with you,

MARJORIE:

I'm the same as you are, tears come to my eyes

When I see professors chasing helpless butterflies.

Fishermen are hateful, they lead a wicked life,

Why, ev'ry day they separate the husband from his wife!

Never swat a fly,

He may love another fly,

He may sit with her and sigh the way I do with you.

Never spray a nit

With a great big can of Flit,

He may think some nit has "It" the way I do with you.

Never stop a moth as he is gliding through the air,

He may have a date In someone's flannel underwear, be careful!

Don't you dare to slay

Two skeeters while they play,

They may want to make hey-hey the way I do with you!

Two questions arise:

(1) How exactly does a bug, when making hey-hey, evince that sexy quality known as "It"? With flirtatiously fluttering ganglia?

(2) Even more puzzling: What was the dialogue leading up to this number? This question has me so flummoxed that I'm throwing it open to my readers. A valuable prize awaits anyone who can create a believable exchange connecting Never Swat a Fly and a futuristic flight in a dirigible. For the sake of this contest, we're assuming that the song was logically integrated into the plot, and not just randomly interpolated. (The latter is far more likely.) The best I can do is this:

"Oh, look, honey! We're flying so high the people on Earth look just like ants!"

"Funny you should mention ants. I've been thinking..."

No, that won't fly.

This contest is open only to those who've never seen the complete film. That's probably 99.44 percent of my entire readership (in other words, optimistically speaking, roughly nine people). Each entry must be accompanied by two box-tops from Kellogg's Pep. In case of a tie, duplicate prizes will be awarded.
