Pat Bastard and the Spurious 5: Thank God It's Friday The 13th: 13 Moar Facts About Jason!!!

At least 100 years ago, I wrote an article all about Crystal Lake's most famous son. Watching the Friday the 13th movies for the 600th time, it occurred to me that there were things I hadn't mentioned, so here they are. Spoilers blah blah blah

Jason doesn't know which side of the machete is the cutting side. He kills two people with the wrong edge of the machete in Part 2, but it works anyway, because he's Jason and he can do anything the script requires him to. Seven films later, he did the same thing again, making it a recurring character trait (intentionally or otherwise).

Would this hurt more or less than the correct way? Pls comment (it's for a friend).
Jason hates rabbits. Part 3 implies that he killed two rabbits just because he hates them. Part 2 also implied he killed a dog, although Kane Hodder says no, and who are we to argue? Anyway, it's clear that Jason will kill animals, and probably trees and shit, when people aren't around.
Jason's hockey mask was supposed to turn up in the otherwise unrelated Friday the 13th TV series, which would have revealed it to be haunted, possibly by Jason. Since the series premiered in 1987, and The New Blood came out in 1988 (in which the original mask was finally destroyed), this would have meant that the mask that was slated for the final episode was the one from Jason Takes Manhattan. Since the episode never materialised, the haunted mask is presumably still floating around in the New York sewer system.

They built things to last in those days.
Ever wonder why Jason can be chasing someone one minute and then pop up in front of them the next? Well the director of Jason Takes Manhattan confirmed that it's intentional, it's not a continuity error. This means Jason can canonically teleport, so every time he doesn't it's because he forgot.
Jason's hockey mask always has red markings. If you see a guy in a hockey mask who kills people and never talks but with blue markings, that's Fake Jason from Part 5. Fake Jason is not as good as Jason because when he dies, he doesn't come back. It's heartwarming how much fans want Jason over another guy who does the same exact thing.
Jason is only two degrees removed from Kevin Bacon, as his mother killed the guy in Part 1.
Jason spawned his own merchandising tie-ins in-universe, such as these hockey mask hamburgers. Would you pay more for, say, a Gacy-themed hamburger with ketchup clown makeup? People in Friday the 13th films would, because people in Friday the 13th films don't give a fuck.

Jason also modelled this poster for the New York tourist board. They b& it.
Contrary to popular belief, Jason has never used a chainsaw, but Ginny from Part 2 chased him with one for a bit, revealing the interesting fact that Jason is afraid of chainsaws.
If you catch Jason between bodies (or, rather, he catches you), he will shave you.

???
Jason has spoken once, while in another person's body. He didn't say anything of interest, but it proves he knows how to speak, he just doesn't.
Some people believe Jason's mother brought him back using the Necronomicon Ex Mortis from The Evil Dead, because it can be seen in the Voorhees house in Jason Goes to Hell. This idea would be revisited in the Freddy Vs Jason Vs Ash comics. However, the filmmakers deny it and we know The Evil Dead is just a movie in the Nightmare on Elm Street continuity, which first crosses over with Friday the 13th in JGTH. What this means is that Mrs Voorhess was actually a big fan of the movie Evil Dead, and had procured the prop at great expense.

Yes.
Jason's father is Elias Voorhees. He was supposed to appear in an early draft of Jason Lives. According to Betsy Palmer's own backstory, Pamela met him in high school. Elias is still alive as far as we know, he just never bothered to call.
According to this thread, Alice may have stolen Mrs Voorhees' ring, thus giving Jason another reason to find and kill her. Sadly this is proven not to be the case: they just had similar rings. But it would be really funny, and when I make my slasher movie series I will definitely have a Final Girl steal a ring from the killer or something.
