Someone please explain why this song refrain is running through my head...

I got this really great gun-
Shit, where is it?
No, it's really great-
Wait-

Shit, where is it?
Anyway
It's just a .38-
But-
It's a gun.
You can make a statement-
Wrong-
With a gun-
Even if you fail.

It telss 'em who you are
Where you stand.
This one was on sale.
It- no not the shoe-
Well, actually the shoe was, too.

No, that's not it-
Shit, I had it here-
Got it!

Yeah! There it is! And-

All you have to do
Is crook your little finger,
Hook your little finger 'round-

Shit, I shot it...

- You can change the world.
