I'll bite
Ever had cat poop brownies? For Halloween? I work for a 99 year old store, where we sell a wide variety of useful or fun items for locals and visitors, such as t-shirts, hats, socks, jackets, bags, hiking poles, footwear, and bear poop (chocolate covered peanuts) with our name on the bag. So, several years ago these 2 ladies were shopping before Halloween and saw the bear poop and were very excited and bought some. They told me they have a party each year and serve cat poop brownies, and the bear poop would be a nice addition. They explained they got a fresh litter box and scooper, which they keep with their holiday or baking supplies. After experimenting, they recommend using grape nuts cereal as the litter (they might have added something else) and Ghirardelli brownie mix as the cat poop; cutting strips after baking and rolling it when it's still warm so they look like poop and tossing them in the litter box. It sparked such laughter, and conversation about poop and pot brownies and not wanting people to eat cat poop by mistake. They brought me some in a poop bag after Halloween. It was tasty! Some might think it's just gross, and I wouldn't go to the trouble of preparing them, but it is funny. And looks very real.
My scariest was 25 years ago, at the Halloween parade in NYC which I usually attended. 2 friends and I went down a side street to get closer and ended up in a crush of people. Crowds are one thing, but a crush or stampede is totally different. Very scarey. And during Halloween with a bunch of costumed or masked revelers made it scarier. Not sure who got the idea, but my 2 male friends picked me up like a battering ram, one held my legs and the other my upper body and they got us through the crush, my feet first. It's kinda funny in retrospect, but I was scared for my life that Halloween, never felt that way before or since. It didn't make me avoid crowds, but I avoid parades and areas where that could happen again, even before covid. I don't like horror or scarey movies, don't want that in my head.
Another Halloween a boyfriend's 13 year old was late getting back from his trick or treating, and was with another kid whose parents had arrived to pick him up. We were just starting to get scared when they showed up, proud they each had a pillowcase full of candy. We confiscated the candy as punishment for missing curfew and making us worry and embarrassing us with his friends family, and that child was not happy! We returned it after raiding it. Good times!
