Just for fun, here's a sentence from my Editing Tips web page that I use 
to illustrate affect/effect differences (as a joke, not seriously!):

"An effective treatment for phobias is to use desensitization therapy to 
effect the desired affective response, having a beneficial effect on the 
patient's affect."
