Ok, but only cos you're my friend:
In jungle cruise , the backhalf of a 'Lockheed' Plane is there, bought especially for it. The front half is in the Casablance scene in 'The Great Movie Ride'.
If you look up at the cemetary gate when you are first going into the cemetary scene of the Haunted Mansion, you can see a paper tag hanging off of the gate. That is actually the purchase tag that was accidentelly left on the gate when it was purchased from a California manufacturer. It has been there for so long, they leave it, as a private joke to themselves I guess...
