Tonight, let's keep it simple: videos of people screaming, and screaming, and screaming. But fun! And often NSFW due to language.
Michael J. Fox in the Back to the Future movies screaming. Note: PG-13 language throughout.
Hugh Jackman gettin' his scream on. Includes indulgent Wolverine violence, of course. And an ad at the beginning.
Leo yelling himself hoarse. Note that the video asks you to confirm that you're over 18, presumably because of the tons of swearing and violence and stuff. It starts out with your vanilla screaming, then gets right into the swear-screaming.
Movie magic is easy: just scream "no" until you can't scream anymore.
If you haven't seen this, you haven't lived.
It just keeps happening. Fun tip: play this one and the video above simultaneously for twice the goat weirdness.
