Mine would be the time my dad rigged a harness and “hung” himself from the carport beam, dressed to look like a stuffed Halloween decoration. He would grab at the bigger kids and parents when they came up to the door for candy. Scared the living bejeezus out of them.
Probably all the times I went to Spirit Halloween growing up. I really loved all the squishy gross-out toys, like creepy crawlies and rats.
One just opened in the old Rite Aid building near me. I haven’t gone in one in ages. I may wander in just to look around.
