There is surely an explanation, but just watch this for one moment, unadulterated by context, and enjoy it. It's wonderful. The inexplicable behavior from the host and Ronaldo's 1,000-yard stare momentarily interrupted by a blink that says what the actual fuck? Amazing.
OK, so, context: Ronaldo went on a Japanese television show and brought with him some kind of device for "facial fitness." He also brought some other massaging tool that looked like an upside down phallus and rubbed it on a lady's face. And, yeah, he stood next to a shirtless, life-size picture of himself for pretty much the whole time.
