When Real Madrid star Cristiano Ronaldo isn't showing off his well-toned muscles after winning a soccer game, he's showing off a gadget meant to help people boast his winning smile.
The Portuguese footballer recently appeared in a Japanese advertisement for an unusual little product called Pao Facial Fitness. It requires users to bite down on a winged contraption and then vigorously nod their heads in an attempt to build up cheek strength. Based on the commercial, it seems that users are also encouraged to dance around.
If you don't want to buy one of these, don't worry: just watching the video is likely to make you smile so hard that you'll get a facial workout for free!
