I've tried to make a parody of "don't worry, be happy", but who concern inflatables.
(I'm not native English, so, please send me pm in case of typo/errors)

Don't worry be happy belongs to Bobby McFerrin

Here's a parody I wrote
You might want to read it note for note
Don't worry, be squeaky
In fleshy life we have some trouble
Being human just make it double
Don't worry, be squeaky
Don't worry, be squeaky now

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky

You can become your own bed
Isn't it funny to be inflated?
Don't worry, be squeaky
A little sad about your fate?
Like your futur is trapped in a net
Don't worry, be squeaky
(Look at me, I'm squeaky!)

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky

(Give you a air compressor
When you worry, use it, It make you squeaky)

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky

You have the fear of spine and thorns?
Well no problem you can reform!
So don't worry, be squeaky
You'll give some happiness
All the kids I see can witness
Don't worry, be squeaky

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky

Here's the parody I wrote
Please sing it loud note for note
Don't worry, be squeaky
My mind is focused on the sky
I'm floating up and say "goodbye"
Don't worry, be squeaky

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky

Oo, oo-oo-oo, oo-oo-oo, oo-oo-oo-oo-oo-oo
Don't worry
Oo-oo-oo-oo-oo-oo-oo
Be squeaky
Oo-oo-oo-oo-oo
Don't worry, be squeaky
