Chords are the same (G D Em C) most of the time but they do change between the 
chorus and the next verse(G D C D). And at the Bridge.

No Capo


Verse 1:
G                    D   
All the girls in the bathroom talking
Em                         C  
who they gonna take to the Sadie Hawkins
G                          D 
My ears are burning but I kept on walking
Em                       C   
smile on my face and an air guitar rocking

Chorus: 
G
The Sadie Hawkins Dance
D 
in my khaki pants
Em 
There's nothing better
C      C 
oh oh oh
 
G                  D
The girls ask the guys
Em              C
 it's always a surprise
G                D
There's nothing better
Em                  C 
baby do you like my sweater?
 
G D C D

V2:
Sitting in the back of my next class napping
 Got up, gave a speech, then bowed to the clapping
 Told a funny joke got the whole class laughing
 think I got a tan from the light which I was basking
 
CHORUS

G D C D

V3: 
Scan the cafeteria for some good seating
 I found a good spot by the cheerleaders eating
 The quarterback asked me if I'd like a beating
 I said that's one thing I won't be needing
 And since I'm rather smart and cunning
 I took off down the next hall running
 Only to get stopped by a girl so stunning
 only to get stopped by a girl so stunning

Bridge: 
G                  D            Em        C
She said, "You're smooth, and good with talking.
G               D        C        D
You go with me to the Sadie Hawkins?"
