I've gotten stuck for a little bit on a few rides, but on my last trip to WDW I got stuck on TOT.
Although it was brief, it was the creepiest thing ever.
Our elevator went through the ride like normal, dropped a bunch, landed at the bottom, the "warm welcome back..." scene played. At this point your elevator is supposed to roll back, turn to it side and then you exit. Well, we rolled back a bit, the lights dimmed, and then nothing. We. just. sat. there. In the dark. With a spooky ventriloquist dummy to my immediate right, staring into my soul.
A little girl in the row in front of me said "Are we
in the Twilightzone now Mommy?" Everyone was all "Hello? Little help here!" and then another elevator dropped down in front of us. And we still sat there. We finally rolled further back then turned so we could exit. The castmember didn't say anything to us about it and we missed our photo!
It was only 5 minutes or so, just super creepy, due to the nature of the ride. That ride always gives me the heebie jeebies (heights/dropping) but I don't ever want that to happen again.
...I still managed to go on the ride 4 more times that trip though.
