Weird Al Yankovic - A Complicated Song chords

A COMPLICATED SONG by Weird Al Yankovic
This is my first tab, so don't yell at me. This probably isn't how it's played but I 
think it goes pretty good with the music. This could probably also be played to the 
original song by Avril Lavigne, "Complicated." So, yeah. Enjoy. I guess.

CAPO 1


 Am             Em
    Uh huh ...   extra cheese
Am                Em
Uh huh, uh huh ... save a piece for me

C
Pizza party at your house
F
I went just to check it out
C
Nineteen extra larges
Am
What a shame
F           C
No one came

C
Just us eatin' all alone
F
You said, "Take the pizza home"
C                          Am
"No sense lettin' all this go to waste"
F
So then I faced

C
Pizza all day
    F
And every day
     C
This cheese 'round the clock
   F
Is gettin' me blocked
    C
And I sure don't care
     Am
For irregularity

C (let ring)
Tell me
Am                            C           Em      F
Why'd you have to go and make me so constipated?
                        Am                      C           
Em    F
'Cause right now I'd do anything to just get my bowels evacuated
                      Am        C          E
In the bathroom ... I sit and I wait and I strain
      F           Am           C
And I sweat and I clench and I feel the pain
    Am                         C                 Em
Oh, should I take laxatives or have my colon irrigated?
Dm    Am
No no no

Repeat same chords for the rest of the song. Sorry.. I'm lazy.

I was feelin' pretty down
'Till my girlfriend came around
We're just so alike in every way
I gotta say

In fact, I just thought I might
Pop the question there that night
I was kissing her so tenderly
But woe is me

Who would have guessed
Her family crest
I'd suddely spy
Tattooed on her thigh
And son-of-a-gun
It's just like the one on me

Tell me
How was I supposed to know we were both related?
Believe me, if I knew she was my cousin we never would have dated
What to do now? Should I go ahead and propose
And get hitched and have kids with eleven toes
And move to Alabama where that kind of thing is tolerated?
No no no no no no no
No no no no no no no
No no no no no

I had so much on my mind
I thought maybe I'd unwind
Try out that new roller coaster ride
And the guide

Said not to stand
But that's a demand
That I couldn't meet
I got on my feet
And stood up instead
And knocked off my head, you see

Tell me
Why'd I have to go and get myself decapitated?
This really is a major inconvenience, oh man, I really hate it
Such a drag, now ... Can't eat, I can't breathe, I can't snore
I can't belch or yodel anymore
Can't spit or blow my nose or even read Sports Illustrated

Oh no
Why'd I have to go and get myself all mutilated? (yeah, yeah)
I gotta tell ya, life without a head kinda makes me irritated
What a bummer
Can't blink, I can't cough, I can't sneeeze
But my neck is enjoyin' a pleasant breeze now
Haven't been the same since my head and I were separated
No no no
