Tom: F
   Bass Intro
Then the guitar breaks in with this rhythm:
    D    F    D              F    D
    D    F    D              G    D
Verse rhythm (variate a lot, I think Frusciante used a whammy bar for live
concerts on this song):
     
D                                 F
     D                                  G
     D                                 F
     D                                  G
Chorus (strike each chord once):
C
Bust my britches
E
Bless my soul
D
I'm a freak of nature
        
C
Walking totem pole
E             G
Look and see I think you'll agree
A
Nobody Weird Like Me
After a while, he starts playing this little riff about 4 times:
    
F    C
The pattern is played again but up 2 whole steps near the end before
the big jam:
    
A  D    C  D
Outro
One guitar strikes the 
D chord every now and then while another plays a solo
in 
Dm over top. Make a lot of noise :)
Try this progression:
      
D             Eb         Gb         G
