That is true - my daughter was a CM (MK train conductor) a few years ago, and she still does the two finger point
I've never been a cast member and I still do it! Guess I've been too many times!
Here's my few:
On the right hand side of Main Street, above the Confectionary, is Roy's window. About halfway down on the left hand side is a window for a "Dr. Card Walker Psychiatrist". Then, as is common knowledge, on the right hand side facing the Castle above the ice cream shop is Walt's window. Here's why Card is in the middle: back in California, the boys had offices on either side of Card's. When they would fight, they would always use him as an intermediary. Walt would tell him to tell Roy something and vice verse. Hence why Card was credited as a psychiatrist and given a window between the Disney boys!
In the alcove on the right side of Main Street there's a window labeled as a Tap and Ballet studio. Every so often, the sounds of tap dancing or classical music will drift into this area!
The drop in Pirates of the Caribbean is because you go under the train tracks.
Splash Mountain is registered as a pool!
The Tiki Room is a gigantic lightning rod. The "thatch" is actually metal strips!
At the AK, the thatch on the roofs in Africa is fake, but Disney got real thatchers from Africa to come thatch their roofs! They even had to get special permission from the state because the thatchers worked barefoot, which is against building/construction regulations!
There's something wrong with Bluebeard's gravestone at the Haunted Mansion. Know what it is? His date of death is 1440, before the New World was discovered. 1440 was actually Yale Gracey's (one of the main imagineers on the Haunted Mansion project and the namesake for Master Gracey, the caretaker of the ride) extension number!
