I remember reading and watching my fair share of Goosebumps but nothing really distinct and vivid has stayed in my mind besides a short part of an episode. I could not remember the context but it was the kidnapped kid with the creepy old dude, this thread reminded me it had werewolves so it must be Werewolf of Fever Swamp. The exact thing was the kid talking about his parent's guns, specifically the "elephant gun". This stuck in mind because I was so fucking confused as to what that was a kid and had no internet to look it up on so I had to manually piece together info from my grandparent's book collection.

Also the book with the cover of the executioner coming down the tower stairs because I remember reading that in the hospital when I'd visit my one grandfather while he was in the hospital and he just did not give a single fuck that I was trying to get some kind of connection with him before he died. Got pissed and never finished the book.
