"I wish I could fly": 



SpongeBob: If only I could join you there in the air

Floating free without a care

I wish I could fly

And see things with a different eye



I could fly

So very high

And touch the sky

And never have to ask why it is that I can't fly



"All you need is friendship":



SpongeBob: You don't need a plane to fly 

Plastic wings may make you cry

Kites are made for windy days

Lawn chairs with balloons fly away



Inflatable pants you may as well skip

If you want to fly all you need... is friendship, yeah.
