[Intro: Timbaland]
In all, enthrilling, new, living sound
Kill me with the coo-coochie-coochie-coo
She kill me with the coo-coochie-coochie-coo
Kill me with the coo-coochie-coochie-coo
She kill me with the coo-coochie-coochie-coo
Kill me with the coo-coochie-coochie-coo
She kill me with the coo-coochie-coochie-coo
Kill me with the coo-coochie-coochie-coo
She kill me with the coo-coochie-coochie-coo
Kill me with the coo-coochie-coochie-coo
She kill me with the coo-coochie-coochie-coo
Lights out, TKO

[Verse 1: Justin Timberlake]
Baby, every day in trainin' to get the gold
That's why your body's crazy
But you can't run from yourself, that's where it's difficult, uh
Girl, I can see in your eyes that there's somethin' inside that made you evil
Where did you go? 'Cause it just ain't fair
Over here thinkin' 'bout the shit you say
Don't know why it gets to me

[Pre-Chorus: Justin Timberlake]
It cuts right on my heart, yeah, it hurt, won't lie
Still can't see, think I saw you with another guy
Fair fight, knocked down, then I got over you
Can't fight no more, you knock me out
What am I supposed to do?
[Chorus: Justin Timberlake]
Don't understand it
Tell me, how could you be so low?
Been swingin' after the bell and after all of the whistle blows
Tried to go below the belt, through my chest
Perfect hit to the dome, dammit, babe
This ain't the girl I used to know
No, not anymore, TKO

[Post-Chorus: Justin Timberlake]
I'm out for the count
Yeah, girl, you knock me out
It's just a TKO
I'm out for the count
Yeah, girl, you knock me out
With a TKO
T-TKO
Out for the count
Girl, you knock me out
With a TKO
Now, I'm out for the count
Yeah, girl, you knock me out
With a TKO

[Verse 2: Justin Timberlake]
Baby, now, I really know what we're fighting for
This rematch sex is amazin'
But nobody wins if somebody's heart is swole
'Cause when I see you move like you got somethin' inside that made you lethal
Where did you go? It just ain't fair
Over here thinkin' 'bout the shit you do
Don't know what I got to lose
[Pre-Chorus: Justin Timberlake]
It cuts right on my heart, yeah, it hurt, won't lie
Still can't see, think I saw you with another guy
Fair fight, knocked down, then I got over you
Can't fight no more, you knock me out
What am I supposed to do?

[Chorus: Justin Timberlake]
Don't understand it
Tell me, how could you be so low?
Been swingin' after the bell and after all of the whistle blows
Tried to go below the belt, through my chest
Perfect hit to the dome, dammit, babe
This ain't the girl I used to know
No, not anymore, TKO

[Post-Chorus: Justin Timberlake]
I'm out for the count
Yeah, girl, you knock me out
It's just a TKO
I'm out for the count
Yeah, girl, you knock me out
With a TKO
T-TKO
Out for the count
Girl, you knock me out
With a TKO
Now, I'm out for the count
Yeah, girl, you knock me out
With a TKO
[Breakdown: Timbaland]
Girl
See what you do?
See what you do, girl?
You knock me right out
See what you do?

[Pre-Chorus: Justin Timberlake]
It cuts right on my heart, yeah, it hurt, won't lie
Still can't see, think I saw you with another guy
Fair fight, knocked down, then I got over you
Can't fight no more, you knock me out
What am I supposed to do?

[Chorus: Justin Timberlake]
I don't understand it
Tell me, how could you be so low?
You'd been swingin' after the bell and after all of the whistle blows
Tried to go below the belt, through my chest
Perfect hit to the dome, dammit, babe
This ain't the girl I used to know
No, not anymore, TKO

[Beat Change]

[Interlude: Timbaland & Justin Timberlake]
You knock me out
TKO, TKO, TKO
Wake up, wake up, wake up, wake up

[Chorus: Justin Timberlake, Timbaland, Justin Timberlake & Timbaland]
TKO, I don't understand it, tell me, how could you be so low, damn (TKO)
You'd been swingin' after the bell and after all of the whistle blows
Tried to go below the belt, through my chest
Perfect hit to the dome, dammit, babe

Dammit, babe, dam-dam-dam-dam-dam-dam-dam-dam-dam-dammit, babe)
