Back in the early days of my playing D&D we didn't run storied campaigns. We ran dungeons. Dungeons that required no logic or continuity. All that mattered was fun and keeping the players guessing.
The craziest thing I remember happening was the day our adventurers approached the entrance to a dungeon. Out side of it was a glass phone booth (for the youngsters reading this I have included a picture of what a phone booth is). Next to the phone booth was a spray can of blue paint.Then the phone inside the booth rang and a kobold came out of the dungeon entrance and went into the phone booth. Then one of the players ran up and sprayed the outside of the booth with the paint. The kobold failed his saving throw and died of fright.
Sure, none of it made any sense at all, but it was wacky and fun.
