Logan Paul confronted a beloved WWE legend and told him that he was going to retire him. In response, he got slapped badly, and it wasn't just his face that was bruised in the process.This week on RAW, right before the main event, Jackie Redmond interviewed the 50-year-old legend Rey Mysterio. The WWE Hall of Famer will officially face The Judgment Day's Finn Balor next week on RAW, and he spoke about his plans for the upcoming match while also taking a shot at his "bas***d" son, Dominik Mysterio. This is likely part of the build-up to an upcoming match between father and son.He was interrupted by Logan Paul, who took multiple shots at Rey Mysterio. The Hall of Famer told Logan Paul that he might be the only one more annoying than Dominik Mysterio. Paul said that he was a great father, while Mysterio's own son called him a deadbeat dad. He vowed to retire Mysterio and threatened him, but the legend simply asked him, "Or what?" before using an insult in Spanish that we can't put here. Mysterio slapped Paul across the face, and they were immediately separated as the social media megastar vowed to make the legend pay for his actions.WWE fans are always happy to see the beloved Rey Mysterio, and they were likely even happier to see him slap someone like Paul. Either way, it's great to see Mysterio back on WWE television full-time, and it looks like he's going to have a busy December.This segment is very likely to have a follow-up, and with Paul now officially part of The Vision, things are going to get interesting. His fellow Vision member, Bron Breakker, will get a World Heavyweight Title shot against CM Punk, but only on January 5 next year.
