Lyrics: Britney Spears. Circus. Blur.

Turn the lights out
This shit is way too fucking bright
Wanna put my eyes out
If you wanna mess with my eyesight
Just let me get my head right
Where the hell am I?

Who are you?
What'd we do last night? Hey, yeah, yeah
Who are you?
What'd we do last night? Hey, yeah, yeah

Can't remember what I did last night
Maybe I shouldn't have given in but I just couldn't fight
Hope I didn't but I think I might've
Everything, everything is still a blur

Can't remember what I did last night
Everything, everything is still a blur
(Did last night)
Can't remember what I did last night
Everything, everything is still a blur

What's your name, man?
Can you come here, hand me all my things?
I think I need an aspirin
Better yet I need to get up out of here
I gotta get my head right
Where the hell am I?

Who are you?
What'd we do last night? Hey, yeah, yeah, yeah

Can't remember what I did last night
Maybe I shouldn't have given in but I just couldn't fight
Hope I didn't but I think I might've
Everything, everything is still a blur

Can't remember what I did last night
Everything, everything is still a blur
(Did last night)
Can't remember what I did last night
Everything, everything is still a blur

What happened last night?
'Cause I don't, 'cause I don't remember it
Oh, what happened?

Can't remember what I did last night
Maybe I shouldn't have given in but I just couldn't fight
Hope I didn't but I think I might've
Everything, everything is still a blur

Can't remember what I did last night
(Blur)
Everything, everything is still a blur
(Did last night)
Can't remember what I did last night
Everything, everything is still a blur
