Check out this page that shows numerous great ads. They all are relatively simplistic but use, and perhaps rely, on various visual metaphors.  Many of these are humorous. Which is one aspect of advertising that can be difficult to accomplish; you don't want to come off as cheesy. But then again, no one wants to sit and take their time to read an ad only later to be left bored and confused.

I enjoy an ad that makes you think. You take in the ad first; the visuals, copy, logo etc.. Then you start to piece all this information together. And once you've understood it,  it's like the brand is letting you in on a little joke. It allows the audience to catch on to a narrative, or make a version of their own. All arriving to the same conclusion: buy that product. The trick is, to do this successfully. You don't want to provide your audience with a problem that they cannot solve.
