Just read all 24 pages of this, and I doubt I'm the first one. Great thread! Here are a few I can add:
On the Indiana Jones ride, there is a small area behind the projection screen in the queue which I believe you can only access if you're doing single rider or if you are (or are traveling with) a guest with disabilities. In that area there is a crate labeled "Send to Club Obi Wan." This is a reference to a club in the second Indiana Jones movie; which is itself a refrence to, of course, Star Wars!
Also, I'm surprised no one mentioned the "Wells Expedition" sign on the Matterhorn. It was put there to honor Frank Wells, Disney's President and Chief Operating Officer from 1984 to his tragic death in 1994. Wells was an avid mountain climber, and there is a matching "Wells Expedition" sign on Expedition Everest at WDW, though Everest is the only one of the Seven Summits he was not able to complete in his lifetime. (According to Wikipedia, " bad weather forced his party to give up one day before reaching the summit.") There is also a building at the studio in Burbank named after him that is home to, among other things, a Starbucks where I did daily coffee runs as an intern last year.
My last secret is something most people probably won't care about, but it will amuse weirdos like me.
If you are in line for any
Disneyland ride and there is an emergency exit, and a rope between you and the exit, look at the rope. It probably is split in the middle, with two magnets holding it together. (I assume this is so if someone is sprinting towards the exit the rope won't trip them.) I discovered this by accident when I tried to lean on the rope
and since then if I'm bored
in line and I see one I might dramatically karate chop it! Just be sure to put it back after.
