Feats of strength are standard practice after a night of drinking. It’s best not to execute those demonstrations with your head though.
A few things stand out from this video of a drunk guy blowing up a beer with his nogging. The fact that anyone doubts this will work is astonishing. If you shake a beer enough, the pressure inside the can makes it pretty easy to burst. The real question is, why would someone want to make that happen with their forehead? Sure, Gladiator taught me it’s the hardest bone in the body, but it’s still going to leave you with one hell of a sore neck. And then there’s the real issue. You just wasted an entire beer just to prove you’re an idiot.
