Cristiano Ronaldo stars in commercial for bizarre Japanese 'facial fitness' device

Cristiano Ronaldo was recently in Japan promoting a strange product called Pao Facial Fitness that requires the user to put a winged device in their mouth and bob their head up and down, supposedly strengthening their cheeks.

After unveiling the device on a Japanese TV show, Ronaldo watched as one of the program's hosts demonstrated how to use it. And judging by Ronaldo's reaction, it was either the first time he'd seen someone actually do it or it was the moment that he suddenly regretted some of his life choices.

I've made a huge mistake.

But either because it was too late or the money was too good, Ronaldo has now appeared in a commercial for the device. Yet he's the only person in the ad who refuses to put it in his mouth.

Ronaldo also appears in a commercial for Pao's companion product — a massager that looks like genitalia. And for that one, the company was able to convince him to actually use it as intended.

After watching all of this, I'm about 78 percent sure that it's an elaborate prank at Ronaldo's expense.
