Daniel Johnston - Like a Monkey in a Zoo
i'm having trouble finding the Daniel Johnston version for reference so im going 
by Kathy McCarty's cover, which i think is in the same key anyway but im not certain.

the main piano tune goes a bit like this (give it a swing):

     G       D         C
E  :-----3---2-0-2-3- | ----------------- | 
B  :----------------- | -------1--------- | 
G  :---0------------- | -----0---0------- | 
D  :-------0-0------- | ---2-------2---2- | 
A  :----------------- | -3-----------3--- | 
E  :-3--------------- | ----------------- | 

the tune's just in the top strings, you can improvise the other part.

                    G , D , C
I'm chained to the wall.
( C )                G , D , C
I have nothin' at all.
( C )     G                  D                  C
And my eyes look into the sunset thinkin' of better things to do,
( C )      G    D     C
Like a monkey in a zoo.


                 G , D , C
The days go so slow.

I don't have no friends.
( C )     G           D                      C
Except all these people who want me to do tricks for them ,
( C )      G    D    C
Like a monkey in a zoo.


G , G7

                        C , G/B , Am
And it could happen to you.
( Am )            G
You could be in my place.

No it wasn't always like this,

But I never saw it comin'.

I'm so alone,

Like a monkey in a zoo.


            G ,    D , C
Throw me a peanut.

Laugh and make jokes.
( C )       G             D               C
But I've had enough of peanuts and I'm ready to choke,

Like a monkey in a zoo.


G , G7

                       C , G/B , Am
You come to look at me.

You seem so amused.
G7                       C , G/B , Am
But things would look different
( Am )           D7
If you were in my shoes.


                G ,  D , C
I know its my fault,
( C )         G ,  D , C
But I want out.
( C )         G       D               C
And when I cry out nobody seems to understand,
( C )      G    D    C
Like a monkey in a zoo.

You say I'm cute.

Like a monkey in a zoo.

                        C , G/B , Am
And it could happen to you.

Don't let yourself slip.
( Am )                    D7
Don't keep egg on your face.

I used to be happy.
( C )                     G ,  D , C
I can't remember those days.
( C )    G       D                C
But I sold my freedom for free room and board,
