Machine Gun lyrics

And I'm up and I don't know why,
But I guess that's all that counts.
Looking 'round as I'm holding my head,
And I'm in somebody's house.

The sun hits me like a punch in the face,
With a headache I can't ignore.
Seems almost every weekend my bed is someone's floor.

And I can't keep this up.
I have had enough.
[ Lyrics from: http://www.lyricsmode.com/lyrics/s/sum_41/machine_gun.html ]
Eating cold pizza on the side of the curb,
To cover up my morning breath of gin.
Something doesn't seem to sit with me well,
It's going out the way it went in.
And so I can't keep this up.
I have had enough.

'cause you can count me out, I'm on to you.
'cause you can count me out, I'm tired of
Leaving my embarrassments behind.

Na na na na na na na na na na na na na
Na na na na na na na na na na na na na
Na na na na na na na na na na na na na
Na na blech!
