I don't think Mentos has made a commercial since at least the mid-1990s, but the ads had an unbelievably cheesy and carefree feel about them. If you'll allow me to indulge you in some candy history, they generally had some sort of problem that was easily solved and ended with the main character enjoying fresh breath. Example A)

It turns out that a chase scene from the 1988 martial arts movie Kickboxer works damn near perfectly as a Mentos commercial once it's synced up with the classic Mentos theme song. 

It all makes so much sense now. JCVD wasn't able to win that underground fighting tournament because of his lifelong training, he won because he had the unbeatable fresh breath of mentos!
