Interesting fact....
One of our really good friends is from Germany. She moved here about 10 years ago. Last year, we went to Epcot to eat at the German buffet, and stopped in their store with the German pickles. I asked her if she played "hide the pickle" at their home, and she gave me the STRANGEST look. I said that Disney was selling the pickle ornaments, and you're supposed to play hide the pickle. She said she had never, in her entire life, heard of such a strange thing to do. I told her WDW had a sign up saying it was a German custom...then showed her the sign.
After she read it, she marched over to a couple of the German CM's and started rattling off a conversation in German. Lots of laughter. She thanked them and came back. Apparently, this is NOT something that Germans do, because the group of CMs had never heard of it until they came to Epcot.
So now you know. And knowing is half the battle.
