I was sittin in the kitchen one daaay

And I was itchin to fiiill up my belly
                                                       G
With the pipin hot jelly of the best damn treat in the world

And I saw a stick of butter
                                                      C
And it almost made me shudder and scream like a baby girl 

I dont want a giant penis or a rocket trip to venus
                          F
I dont wanna win the lottery
        
I just wanna squat and gobble

Till im dizzy and I wobble
      G                           C
In a butter, fruit and dough tart dream
