A friend of mine is looking for a job...went on an interview, and was then told that she would not be getting an offer for the position b/c she is too smart and over qualified. I think I've come up with the perfect response:
"Oh, I'm sorry....did you just say that I'm TOO SMART for this job? Good, that's what I thought you said. I'll be sure to email your job posting to every dumb-ass moron I know. Hopefully you'll find some idiot to fill the position."
Hang in there M'Witty!
