Finn: [singing]

 ♫ Is this really my life?

Is this how my story ends?

Bein' in this body,

Seems like a battle that I cannot win.

Maybe I should lay my head down slow,

And sleep until it's all over,

Is this the end,

of the hero boy named Finn?

Heck no! Darn it, no!

This isn't how I go!

I'm gonna kill it! I'm gonna kick life's butt,

And win it, to win it.

I'm gonna take life's name,

And spit on it, and kick it!

Life can just go eat it,

'Cause this is a man's game! ♫
