Allright, I finally finished reading this whole thread, and boy was it hilarious. I have a few of my own to add.
When I was about 14 or so, my family went to eat at the restaurant in the Japanese Pavillion (can't remember it's name right now...the one where they cook your food in front of you). There are 6 people in my family, so they put a couple on the end of our table to fill it up. My dad just happened to be sitting next to them. Now, my dad is quite the goof ball (and very outgoing), and likes to embarrass my mom (and boy is he good at it). Well, it turned out that this couple was from Japan and didn't speak English. So my dad starts trying to tell them where we are from. He holds up his hand and points just below his thumb to represent Southeastern Michigan, and starts describing it this way: "We come from Mi-shee-gan. FAR away. Land of many lakes," while trying to gesture out the lakes surrounding his outstretched hand. We felt like we were in one of those old cheesy western movies. The poor people probably think all Americans are nuts now. Or at least all the ones from Michigan.
Another classic occured a year ago when my best friend and I visited WDW for our senior Spring Break. She likes all of the thrill rides, but gets kind of freaked out in the dark. So, the second time we rode ToT, when the elevator stops on the way up and you see the family disappear, I grabbed her arm just as the window shatters. She screamed so loud that everyone in the car was staring at her like she was crazy because we weren't even to the dropping part yet. I was laughing so hard that I had tears in my eyes. I didn't stop laughing until we were on the other side of the park.
My family also made a trip for Christmas 2003. A rather unfortunate family tradition is to dress up in seasonal costumes to take our Christmas card picture every year (we've been snowmen, angels, reindeer, etc.). Since our house had been under construction we hadn't had a chance to take the picture at home, so my parents packed up 6 big cardboard boxes (so we could be presents) from our new kitchen cabinets and hauled them with large rolls of wrapping paper down to WDW. We checked into Fort Wilderness, set up our camper, and then they brought out the boxes. We taped them up, wrapped them, and then my mom had the brilliant idea to take the picture in front of the huge Christmas tree they had over by Pioneer Hall. So, we each took our box, and we hiked all the way up there past all of the people sitting around their campers, and set them up inside the fence in front of the tree (down by the marina, so TONS of people going by). My brother and I were so embarrased, that we were pretending to be British exchange students and commenting on our crazy American host family. To make things worse, once we got all set up, some man came over and offered to snap our whole roll of film off for us. I just about died when we took the roll to the Sam's club (or is it Costco?) nearby and had it one-houred. Then we ordered the cards, and they hung up our picture for everyone to see. I thought I'd be scarred for life, but I've gotten over it somewhat.
I'm sure there's more...but I can't remember any right now...
