That YouTube video has an age restriction, so you need to sign in and confirm your age before you can watch it. It's usually for content with mature themes, strong language, or graphic images, and YouTube adds that to follow their guidelines. If you're logged in and still can't see it, your account might not meet the age requirement yet.
