"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.
