If so, you should try to find (or create yourself) an advertisement that's BLATANTLY not "politically correct".
That is, have an advertisement or office scene where you have a group of 10 employees at a meeting, etc. but all of them are white males!
I think that would be hilarious. You know how they ON PURPOSE throw in a mix of every race and gender combination -- it gets old after a while. And it's seldom realistic (e.g., a group of engineers, computer programmers, etc.)
