You’ve been warned
This explanation is as good as any other. Joking aside, Chuck Norris obviously did not break this bench, but he’s certainly capable of it, and so whoever put up this sign is pretty clever. Over the years, endless jokes have been made regarding Norris’ strength, and frankly, we think he should be complimented by them.
Every other person in the U.S is a fan of Chuck Norris, and so the jokes are made out of admiration and jealousy (well, for the most part). He is so powerful, whenever something massive breaks, it makes sense to blame it on him.
