I have two stories. The first falls into the "plain weird" category, but wasn't in queue.
Last trip, we were staying at Caribbean Beach. We had returned to the resort that afternoon for a little bit of relaxation before heading out to our evening dining reservation at EPCOT. We got ourselves ready and then opened the door of our room so that we could leave only to find a mother and her kids sitting on the floor in the little alcove between our room and the room next door. One of the kids was actually leaning against our door and almost fell into our room when we opened it. As we headed out, the mother simply says to us - perhaps in response to our confused looks - "there was a serious problem with our room" and that was it. I think we smiled and then headed to the bus stop. They had gone by the time we had returned later. Never found out what the problem was.
The second story was neither ridiculous or weird, but it was an amusing in-queue interaction with some other guests:
On the day we arrived at WDW on our last trip, we headed to EPCOT. After riding Spaceship Earth, we went towards the Land pavilion and to our surprise, found that Soarin' was only a 15 or 20 minute wait. So, despite running on adrenaline by this point, we headed towards the ride. Just behind us in the queue was another rather excited family. The kids were playing around in the queue, but they were not bothering us too much. We started chatting to the other family and they guessed correctly from our accents that we were from the UK. We continued chatting for a little longer while the kids were still playing around. Evidently the parents thought the kids were getting in our way, because they said to them "look kids, stop attacking the Brits. We gave that up in 1776!"
