Just after Gandalf takes the spell off Theoden, he makes an attempt to kill Grima Wormtongue. As Theoden stands over Grima with his sword, all of a sudden Grima jumps up and starts singing…

Lucky you were born right here in Rohan
So I could come control your mind.
Lucky that I love a foreign land
So I didn’t grumble when I stayed here.

Baby I would climb the Blue Mountain solely
To help you with your corrupted plans.
Never could imagine there were only
Ten Million ways to take over somebody.

Le do le le le le, Le do le le le le
Can’t you see
I’m at your feet

Whenever, wherever
We’re meant to stay together
I’ll be there beside your throne,
Whipering secrets in your ear.

Thereover, hereunder
You’ll never have to wonder
I’ll tell you all the answers here
But that’s the deal my dear

Lucky that my lips not only mumble
They tell secrets like a fountan.
Lucky that my plans are small and evil
So you don’t confuse them with good ones
Lucky I have strong legs like my mother
To run for cover when I need it
And these two eyes see the evil in you
The day you were released I cried a river.

Le do le le le le, Le do le le le le
Can’t you see
I’m at your feet

Whenever, wherever
We’re meant to stay together
I’ll be there beside your throne,
Whipering secrets in your ear.

Thereover, hereunder
You’ll never have to wonder
I’ll tell you all the answers here
But that’s the deal my dear

Le do le le le le, Le do le le le le
Oh can’t you see, please don’t kill me!
