     A 
Just knocking 'round the zoo 
On a Thursday afternoon 
There's bars on all the windows 
And they're counting upon the spoons 
D 
If I'm feeling edgy 
                              A 
There's a chick who's paid to be my slave 
           E 
But she'll hit me with a needle 
       D                                A 
If she thinks I'm trying to misbehave  
Verse 1: 
        A 
Now the keepers trying to cool me 
Says I'm bound to be alright 
I know that he can't fool me 
'Cause I'm putting him uptight 
      D 
I can feel him getting edgy 
Every time I make a sudden move 
          E 
And I can hear him celebrating 
       D                        A 
When I finally up and leave the room 
 
(Chorus) 
 
Verse 2: 
Now my friends they all come to see me 
They point at me and stare 
He's just like the rest of us 
So what's he doing in there? 
Now they hide in their movie theaters 
Drinking juice and keeping tight 
Better watch out for the bright light baby 
Because they're certain about one thing: 
The Zoo's no place to spend the night, no 
 
(Chorus)
