"Screw you! I'm gonna poison my lungs! <takes a draw on a cigarette> Take that!"
Hmm....take that....there's an idea. Whenever you feel like smoking, put a Take That cd on (I suggest you get some poor sucker to obtain it for you so you don't get stoned *as in rocks* to death). Then eventually you will associate fags with fags (if you'll pardon the expression) and that might help you quit.
