She walks down to the store at 8
The devil walks with her and he thinks she’s great
When she looks at me I don’t know what I saw
I think he’s tryin’ to make me his son-in-law

Chorus
(do a pick scrape on the fifth and sixth string) 
C    A     G   F    C    A  G             F
Walk by   Walk by   Walk by she walked on by

Play main riff
verse riff
Egos fly when she walks by
She cut my eye on October ninth
22 days before Halloween 
how did I know she’d be my evil queen

Chorus
C                G          F
My mother warned me against girls like you
         C           G               F           
She said stay away from them son you know they’re untrue 
C                 G             F              C          G                     
All they’re gonna do is put you under a spell When you’re fallin down you’re goi

Just listen to the song and you’ll get it.   Good Charlotte Rocks!
