It may be a little early, but you don't have to change too many words.

It pretty much writes itself.

you better watch out
you better not cry
you better not pout
I'm telling you why
nsa is tapping your phone

He's making a list,
He's checking it twice,
He's gonna find out
who's naughty or nice.
nsa is tapping your phone

He sees you when you're sleeping,
He knows when you're awake.
He knows when you've been bad or good,
So be good for goodness sake!

you better watch out
you better not cry
you better not pout
I'm telling you why
nsa is tapping your phone

Every breath you take
Every move you make
Every bond you break
Every step you take
I’ll be watching you

Every single day
Every word you say
Every game you play
Every night you stay
I’ll be watching you

Oh, can’t you see
You belong to me
How my poor heart aches
With every step you take

Every move you make
Every vow you break
Every smile you fake
Every claim you stake
I’ll be watching you

Since you’ve gone I been lost without a trace
I dream at night I can only see your face
I look around but it’s you I can’t replace
I feel so cold and I long for your embrace
I keep crying baby, baby, please...

Oh, can’t you see
You belong to me
How my poor heart aches
With every breath you take

Every move you make
Every vow you break
Every smile you fake
Every claim you stake
I’ll be watching you

Every move you make
Every step you take
I’ll be watching you

I’ll be watching you
I’ll be watching you
I’ll be watching you
I’ll be watching you...
