All work and no play, allegedly, makes Jack a dull boy. And advertisers seem to agree; globally, major brands seem more interested in making us laugh than selling a product; and for good reason: humor is one of the best ice-breakers. If a brand can make you happy, they can make you open your wallet.

With that in mind, ad execs often turn to the humorous, irreverent, or even outlandish to break through the clutter and demand attention. Sure, sometimes jokes fall flat; but do it well, and the effect goes beyond the eyes — to the brain, to the emotions, and most of all, to behavior change.

And so, for a bit of Friday fun, we thought we'd share some amusing, irreverent, strange and comical adverts from around the world. Enjoy!
