The "Songs that are Better with Ninja" meme

It's just a fact of life.  Some songs, particularly some of the most annoying songs out there, can't be improved with covers or altering the arrangements.  They need NINJAS to be made palatable.

Here's a couple examples:

 

Just call me ninja of the morning NINJA
just touch my cheek before you slay me, ninja.
Just call me ninja of the morning NINJAPost an Entry
then slowly turn and hide from me.

 

See?  Here's a more modern example:

So,
So what, I'm still a ninja
I got my ki moves
And I don't need you

So that's the start.  Your task is to find those annoying earworms that can be improved by inserting ninjas into them.  Then go ahead and share them here.  Go!
