"It's what mosquitos would use on mosquitos they don't like."
It's easy to be complex but difficult to be simple. This campaign by Leo Burnett Warsaw, Poland for Bros Mosquito Repellent strikes precisely with its simplicity of thought. We all have pet peeves and you can't deny that there are some people you just dislike so much that you'd start thinking of bad things you'd want to do to them. And the illustration speaks a lot while still complimenting the copy. I love it.
