I agree with eirikws...and as for the change in the last bit where it says "I just want to be tied to the back of your car," well...murder has been committed by tying a person or animal to the back of a car, so i think it's a morose comment hinting at the fact all of the crap mentioned in the rest of the song makes him want to die, and he wants the person he's singing about to put him out of his misery.
