There's a ludicrous amount of fan theories floating about the wider world of Harry Potter. With even J. K. Rowling getting in on the joke, both the author and readers alike have retroactively tampered with characters in a myriad of ways, providing plenty of Harry Potter machinations that give way to bizarre, dark secrets.
Of course, whilst not all of the entries on this list have the wizarding queen's seal of approval, they're still certifiably ridiculous when considering the franchise as a whole - and while most provide a good laugh or quiet reflection on everything you hold dear, there's some that just take the magical biscuit. There's an underbelly out there rife with 50ps that represent the resurrection stone, Harry being Ron's hallucination, and Dumbledore being a time travelling ginger. Of course.
It takes a lot to be the most ridiculous when every theory creates a new high, or low, for crazy conceptions involving the Potter crew. Either way, swallow your gillyweed and have your wand at the ready, because we're wading into the weird and wonderful world of Harry Potter fan theories.
8. Hufflepuffs Are Competent With A Whole Variety Of Herbs
This one is really low-hanging fruit, so please, just bear with me. In a world full of magic, adventure, beautiful creatures, amazing fauna, and endless possibility at one's fingertips - Hufflepuffs would apparently rather take the back seat and just chill out. Magic can be stressful, I guess. Regardless of the reasoning, Hufflepuffs are known for a few important things: their kindness, calmness, and of course, their green fingers. See where I'm going with this yet?
There's literally a theory that has decided Hufflepuff is the house of all things herbivore in more ways than one. Cultivating plants as their passtime, there's belief that they'll obviously run across the devil's lettuce at some point or another - or maybe even the magical equivalent... Voldemort's cabbage. I don't know.
So yeah, Hufflepuff is the house of stoners. The reasoning for this is that the common room is right next to the kitchen for when those pesky munchies kick in, and, if that doesn't convince you, that PUFF is literally in the name. Explains why they're so nice and friendly all the time, apparently.
