I have two of them:
the funniest one was when I got stuck in IASW, we stopped moving and the audio kept on going, i swear that my mind was about to explode, I mean I love the IASW song but only in small doses!
the second one, I was with my brother and we went on Soarin' for the annual pass preview, we had to do a 40 min line, and after we got on the ride, right after the golf scene, the screen whent pitch black but the audio was still going and there was still movement. We stayed up there for about 7 min. in the dark, in the dark so dark that you can't even see your hand in front of you, but after that, they turn on the lights and leave us up there for another 5 min with the audio still one but the ride finally stopped moving. After this they finally bring us down, but they asked us not to move in case they could get the ride working again, so again we waited even longer, until they finally let us go, by then I was really annoyed as well as everyone else who was stuck in the ride. So we are outside of soarin' they tell us to wait for a manager to talk to him about how we could ride soarin' again, nothing was solved, they just told us that they were evacuating the building and they took us backstage where they told us that someone would come outside to talk to us, but after waiting backstage for the manager, security come up to us and tells us that we have to go back in the park, so at the end nothing was solved, I got to see Journey into your imagination backstage, but only that.
