I was on the beach one day and I found a calculus book.  So I opened it up with my flipper.
C            Am       Em                                     G
Then I saw a problem: find the derivative of x squared minus 3x.
              C               Am                   Em             G
I didn't know what to dooooooooooooooooo so I went crazy.  And it sounded a little 
something like this.

     2x minus 3         That was the answer         Why'd I go crazy?
