Perhaps a bunch of dehumidifiers will fall on the Seven Dwarfs and instantly
crush them to death, and then the whistling will thankfully come to a
peacful halt. Now that's true happiness! grin

Perhaps this one was built by the Seven Dwarfs ("Whistle while you work")?

Just whistle while you work
And cheerfully together we can tidy up the place
So hum a merry tune
It won't take long when there's a song to help you set the pace

And as you sweep the room
Imagine that the broom is someone that you love
And soon you'll find you're dancing to the tune

(Spoken: Oh, no, no, no, no! Put them in the tub)
When hearts are high the time will fly so whistle while you work
