I've been laughing at this thread for days so I guess it's finally time to post!
I have two embarrassing stories, one for me and one for DH.
Mine - As background, I need to tell you I hate being scared. I won't go to horror movies, or in haunted houses (except HM, and even that creeps me out), etc etc. After many trips to DW, DH finally convinces me to go on that alien thing that was where Stitch is now (I forgot what it's called - Alien Encounter?). It's crowded, so the CMs make us file to the end of the row and fill in every seat. DH goes in first and sits in his proper seat, but the seat next to him, where I should have sat, has a cloth draped over it with a warning sign about how the seat is broken, so I have to sit on the other side of it. So, now there is a broken seat between me and DH. However, I'm totally convinced that this being Disney, the seat isn't really broken, it's part of the show, and an alien is going to pop out of that seat. So I'm freaking out, telling DH I'm going to kill him for dragging me on this attraction, practically crying, and the people behind me are laughing hysterically (though to give them credit, they tried to hide it). The show starts and the lights go down, and I spend the next few minutes braced for the alien popping up next to me. The show ends - no action from the broken seat. Turns out it really was broken.

DH never asked me to go on alien encounter again, though.
DH's - We're eating at Mama Melrose, DH gets up to go to the bathroom, and doesn't come back for a long time. I'm starting to get worried when he finally returns, and when I ask him if everything is ok he says yes, so I put it out of my mind. Finally, somewhere around dessert, he says to me "I was attacked by a toilet, that's what took me so long."

Turns out when the toilet flushed it sent water spraying all over, and got his underwear so wet he had to take them off and stuff them in the trash. (I can only presume they're the automatic toilets and one of them flushed prematurely, but honestly I didn't get into too much detail - I was too busy laughing at him going commando). DH is actually really modest, way more than me, so he was pretty uncomfortable going around commando for the rest of the night.
I guess we both just attract broken "seats."
