That's 40 years of Crazy Ralph screaming You're all DOOMED, Pamela's headless body reaching for the non-existent noggin', that one soggy jumpscare and Kevin Bacon getting throated with an arrow.
It's a landmark! Makes me sincerely proud to be a fan!
HAPPY BIRTHDAY, FRIDAY THE 13TH (1980!) MAY YOU CONTINUE TO BRING BLOODY JOY TO US ALL!
