Intro:
-nc-
The itsy bitsy spider went up the water spout
 
Downed all the beer to drown the voices out
 
Up came the sun and brang back all the pain
 
So the itsy bitsy spider went out to drink again
 
Interlude: B  Gbm  Em

Verse 1:
B                 Gbm
Stuck in a cycle, no one can tell us the way that this might go
-nc-
And everyone looking at me like I'm psycho
B                            Gbm
You know you should be better, you know you gotta change
Em
You knew I wasn't ready, I knew you'd never stay
B                    Gbm
You knew I wanted more than just your web of lies
Em
So I'll say goodbye
 
Pre-Chorus:
B         Gbm
One shot, two shot, three
Em
Feel those bad feels leave
B           Gbm
Four shots, nine shots, eleven
Em
Just can't learn his lesson
 
Chorus:
    B                      Gbm
The itsy bitsy spider went up the water spout
Em
Downed all the beer to drown the voices out
B                   Gbm
Up came the sun and brang back all the pain
       Em
So the itsy bitsy spider went out to drink again
 
Verse 2:
B                      Gbm
Creeping and crawling, head in the toilet, you might just fall in
Em
Mama been calling, wish I could take it back, not what she wanted
B                                  Gbm
Dreaming of drinking, what are you thinking?
 
Back of your mind be confessin'
Em
You know it ain't worth it, she don't deserve it
 
Caught in your deadly obsession
 
Pre-Chorus:
B         Gbm
One shot, two shot, three

Feel those bad feels leave

Four shots, nine shots, eleven
Em
Just can't learn his lesson

Don't make this harder than it has to be
          Gbm              Em
You got until the count of three
 
And by the end I'm leavin'
