WWE is full of unwritten rules that go without saying, but they also go without questioning. If you need a weapon or a prop, you’ll find it under the ring. If a wrestler goes through a table, it’ll likely be the Spanish announcer’s table first. And if you try to head-butt a Samoan, you’re gonna have a bad time. Their heads are indestructible! Heaven forbid a Samoan head-butt another, or the result would be utter annihilation! Jimmy Uso, Jey Uso, Roman Reigns, Umaga: all of these Samoans no-sell a headbutt, and it’s usually the opponent who goes down instead. Check out who has The Hardest Heads In WWE!
