I just remembered another one...
In line for E:E at the Yeti Museum, first you pass a lot of real artifacts of the famous supposed Yeti. Well, the family in front of me seemed really into the attraction and was checking everything out. Anyways, the line was moving kind of slow so it took a bit.
One of the adults (there were about three in that party --with two kids (I'm guessing about the ages of 15 and 9)).
One of the adults was commenting on how everything was real.
Once you pass most of the line in that area, we came up to the "Lost Expedition of ____". (I forgot what year they said it was). It's the part with the ripped up tent, and broken gear. On the wall there is a small plaque that says something like "these are the only remaints of the lost expedition of ____. All of the expedition members went missing. A camera was found with only a few pictures in it. The pictures were developed, and this is what they were of..."
To the side of the plaque shows some blured pictures of half the yeti's head, and parts of his upper body. (The AA in the ride of coarse)
Well we got to there, and one of the adults read it outloud to everyone. And said something to the effect of "oh yeah"; like she remembered reading about that expedition elsewhere or saw something on TV about it. It was funny because the 15 year old (my age) was like "wow! really?" as he took a few second looks at the pictures. Everyone believed it was true.
Just shows what a great job Disney did with that attraction!!
