I heard it in the movie "nacho libre".

here are the lyrics, i googled and copied and pasted them, but not sure of the accuracy -- lisovate? what's that??

Because your there
When I awake
And then you leave me
to lisovate
Because the Children
With you can play
I think
I think I am

Cause when I speak
You're always there
You even listen
What I can tell
You are my gospel
My daily bread
Thats why I think I am

I am I am, I am I am
I think I am I thank I am
I'm glad I am
I'm proud I am
A real religious man

As I realized
The mightiest friend
Can separate
A chance from fate
Cause you have all I need to take
That's why I think I am I am
i am i am
(whoa)

Cause I have prayed I just behave
Cause saints and sinners
Are quite the same
Cause it's my temple
The whole wide world
That's why I think I am I am

I am I am, I am I am
Think I am
I thank I am
I'm proud I am
A real religious man

I am I am
I am I am
I pray I am
I feel I am
Oh Lord I am
God knows I am
A real religious man

I am I am,
I am I am
I pray I am
I feel I am
Oh lord I am
God knows I am
A real religious man
a real religious man
a real religious man
