"Tucker's Kobolds" from 1987 is about giving weak #dnd monsters with (honestly) excessive tricks inc traps. It's a meme now, picked up on YouTube.

Looking through editions, there are zero references to kobolds using traps before it. #odnd just says they are weaker than goblins, basically the crappest humanoid. #adnd1e has them just fighting. #bxdnd says they "ambush". All before 1987. But #adnd2e (1989) has heavy reference to traps for them. TSR eating their own memes.
