isnt as detailed in givng you the chords so here is the exact way to play. Note that 
Stephen uses a D or a Dsus2 so ill show you both in different verses(which i think
is how he plays it) It sounds better if you don't fingerpick it

Lyrics:
Verse 1:
(Main Riff 1A)
I bought a grebil at the petting zoo
If Richard Gere can do it i can too
I got undressed, I start to lube
I stuck the gerbil at the end of the tube

PreChorus 1:
Wondering just how he'll feel
Will he like it better in his little wheel
Careful now he's right beside me
One more inch and, he's inside me

Chorus 1:
Burrow harder, burrow deeper
Be my little chimney sweeper
One thing I forgot about
How am I supposed to get you out

(Main Riff 1B)
Verse 2:
He's warm and cozy and there's plenty to eat
The situation is beyond my control
Gotta find a way to get him out of his hole

PreChorus 2:
I tried crowbars, I tried wires
I almost hurt him with a pair of plyers
I tried cheese but he's not biting
I wish this wasn't so exciting

Chorus 2:
Jesus I am such a sucker!
Please get out you furry fu----
I think I am getting ill
Suddenly he's very, very still

(Main Riff 1B)
Verse 3:
Now it's too late, my gerbil died
I guess I have committed Gerbicide
Here's some advice, it's very clear cut
If you love your gerbil...(end on Dsus2)
Don't stick him up you butt(Main Riff 1B)
Dont stick him up your butt
Little furry gerbil in your booty-hole
Dont stick him up and...

He just mumbles and scats and you play this by simply strumming the Main Riff Chords- A,G,Dsus2,C)

End on A
